Before or after tax?
Etiquette guides recommend tipping on the pre-tax subtotal. In practice, many people tip on the total, and the difference is small: at 8% sales tax, a 20% tip on the post-tax amount of a $155.00 pre-tax bill is $33.48 instead of $31.00, about $2.48 more. Check whether a service charge or gratuity has already been added, which is common for parties of six or more; in that case no extra tip is expected.
