Frequently Asked Questions

Should you calculate tip on the pre-tax or post-tax bill total?

Etiquette experts recommend tipping on the pre-tax subtotal, as gratuity is intended to reward service rather than government taxation. However, tipping on the post-tax total is also widely practiced and appreciated by waitstaff.

What percentage is customary for delivery drivers and bartenders?

For food delivery drivers, $3–$5 or 15–20% (whichever is greater) is standard. For bartenders, $1–$2 per beer/wine or 18–20% on open cocktail tabs is customary.
