I tip generously. Usually ~20%, rounded up. At times more; less only for not good service. On the way home from bell choir tonight i stopped for a late dinner. The restaurant has a special after 8pm of $25 for a bottle of wine and a board of 4 bruschettas; normal price for the board is $16, and the wine varies, but is typical restaurant upcharge. When I paid, the card reader 20% generated tip was over $11! Apparently, it did not take the special into account.
Is it normal to tip on full price vs specials like this? I will say that there are some specials (free meals on veteran’s day, for example) where i do tip on the regular price (and i tip about 25%), but that seems different from a regular special. For example, would you tip on full price for happy hour pricing?
