Sorry, R-B , but I beg to differ with you. the C”H occurs when the (often) non-Jewish delivery guy says to himself, “CHEAP JEW!” (And he WILL). It is even worse, when the delivery is of a big bag of restaurant goodies that may have cost 50 or more dollars. You really cannot afford two or three bucks for a tip?????? You just hate the idea of feeling coerced into this by anyone.
