I know this is going to sound petty, but it still drives me crazy! One of the companies I shop for reimburses tip at 15%, not a penny more. If there is a bar receipt, that too is 15%. So.....if you order a soda or beer at the bar and the bill is $4, so they really think anyone, a shopper or not, is going to leave a $ .60 tip??? That is ridiculous! Of course, I leave a dollar or two...it just irritates me that they don't reimburse a reasonable tip. Yet, we are supposed to blend in!!! Okay, rant done!
