Before my career in television news I had a bunch of jobs in restaurants as a bartender, waiter, and bus boy and most of what I earned came from tips. I also worked in a few stores where I was not tipped, just paid a regular wage.

Perhaps times have changed since then, but many people have complained to me, and I’ve noticed too, that they are now being asked to tip at businesses where it wasn’t expected, and there aren’t any wait staff. Some fast food restaurants even have a tipping option when you check out. Not long ago, I bought two pies at a bakery, put in boxes by the women behind the counter. When I checked out, the computer screen asked me about a tip, and the lowest option was 18%.

What do you do in a situation like that? What are the guidelines and proper etiquette? Some are complaining they feel under pressure to tip and shamed into tipping. The ABC station in San Francisco did a story on the proliferation of gratuity requests where some consumers are calling it “emotional blackmail.”

This Sunday on This Week in Connecticut we will get answers from a manners expert, Michele Oricoli. She will answer the questions about when to tip and where you don’t have to. Join us Sunday morning at 10 on WTNH.

For the record, my wife and I are good tippers. Kara worked in restaurants too and we know how hard that work is. I’ll see you Sunday.
