Money, Tipping & Paying Your Way on Route 66 — International Visitor Guide

Two aspects of American financial culture consistently catch international visitors off guard on Route 66: tipping and the gas pump ZIP code problem. Both are easy to navigate once you know the rules. This guide covers both, along with everything you need to know about money, budgeting, and paying your way across all 2,448 miles of the Mother Road.

US Tipping Culture: The Essential Guide

Tipping in the US is not optional in the way it is in many other countries — it is a fundamental part of service industry compensation. Restaurant servers in the US are often paid a sub-minimum cash wage (as low as .13 per hour federally) with the legal expectation that tips make up the difference to a living wage. Not tipping directly harms the workers who served you.

Where to Tip and How Much

Sit-down restaurant (diners, full-service): 18–20% of the pre-tax bill is standard. 15% is the absolute minimum for adequate service. Route 66 diners are the heart of the trip — tip well.
Counter service (ordering at a counter, picking up yourself): –2 is appreciated if there is a tip jar, but not mandatory.
Fast food: no tip expected or required.
Hotel/motel housekeeping: –5 per night left on the pillow or in an envelope marked housekeeping. Widely overlooked by international visitors but important.
Taxi and rideshare (Uber, Lyft): 15–20%. The app will prompt you at the end of the ride.
Gas station attendants: no tip required — most US stations are self-service.

Practical note: the tip is added by you after receiving the bill — it is not automatically included. Some restaurants add a suggested gratuity percentage note at the bottom of the check.

Using Foreign Credit and Debit Cards in the US

US merchants use chip-and-signature, not chip-and-PIN. When you insert your card at a US terminal, you will typically be asked to sign rather than enter a PIN. Most foreign cards work fine for in-store and restaurant purchases. The main issues arise at automated kiosks requiring a US ZIP code — primarily gas pumps. See the driving rules page for the full solution.

Currency: US Dollars only. Exchange at the airport on arrival or use bank ATMs. Avoid airport currency kiosks. Notify your bank before traveling that you will be using your card in the US to prevent fraud blocks.

Carry Cash on Route 66

Many of the most iconic stops on the Mother Road — small diners, roadside stands, historic trading posts, family-run curio shops, some vintage motels — are cash-only or have unreliable card terminals. Withdraw 00–00 in cash at the airport on arrival, keep roughly 00 in smaller bills accessible at all times, and replenish at ATMs in larger towns (Tulsa, Oklahoma City, Amarillo, Albuquerque, Flagstaff) as you drive.

Route 66 Budget Guide for International Visitors

General budget framework for a 14-day Route 66 trip for two people (excluding international flights and pre-booked car rental):

Accommodation: 0–50 per night at a vintage motel or budget chain; 50–50 at historic motor courts. Many iconic Route 66 motels (Munger Moss, Blue Swallow, Wigwam) fall in the 0–30 range.
Food: 0–0 per day for two at diners and roadside stops, including tips. Route 66 diner meals are excellent value — 0–8 per person for a full meal is typical.
Fuel: approximately 50–00 total for a full end-to-end drive. Fuel is significantly cheaper in the US than in the UK, Australia, or Europe.
Attractions, souvenirs, and incidentals: 0–0 per day. Most iconic Route 66 attractions are free. Major costs are national park fees (Grand Canyon: 5 per vehicle), museum admissions, and gifts.

Total daily budget estimate (excluding flights and car rental): 50–00 USD per day for two people. A 14-day trip typically costs ,100–,200 in-country expenses for two people.
