It used to be so simple. You’d start with a 20% tip and either add or subtract, depending on the service provided by your waiter or waitress. Some people are big tippers, some are tightwads, but almost everybody has a system.

Nowadays, though, the tipping lines are getting blurred. In some stores, the credit card machine will ask if you want to provide a tip to the clerk who merely rang up your order. Punch the tip button and you feel like you’re just throwing away money. Press no and you feel like a cheapskate and the whole moment becomes awkward.

We want to hear your thoughts on the whole matter of tipping and how it has changed over the years. Instead of crumpled one dollar bills and loose change, leave your comments in our tip jar by writing Mark LaFlamme at mlaflamme@sunjournal.com or call 200-1481.
