I tip well and in cash. I know that the tips on credit card receipts will be reported, whereas cash is not and the servers are assessed at a lower than 15% rate.
If people want tipping to go away, then restaurants will have to pay servers more and, guess what? Prices will go up. Regardless of service. So, I prefer to show my appreciation for good service with a good tip (usually 20-25%, unless incredible, then sometimes 30%, if awful, then 10-15%). This is just me; although, I have been known to go back and leave extra when the person I am with undertips. lol
I do not go out to eat all that often, so my experience may not be the norm, but most servers around here are working their tails off to make money to make ends meet. I prefer to reward that, in order to make sure it continues. I consider my tip as part of the cost of the meal from the beginning, so no sticker shock for me.
As it should be.
