Typically, I give at least 20% on my total bill. If the service or the waitress is especially charming, maybe more.
I wonder, when you sit at a bar/restaurant and have a meal and drinks and then order a take out ( I do this for my mother quite often) are you supposed to tip on everything, including the takeout??
When I stay in a hotel, I typically leave 2 or 3 dollars per day for the maid. If I get my car valeted, I usually tip $2.
What do you tip? Hopefully, not a Watchtower or Awake!
