Senior travelers often are confused about tipping. In a few countries, it’s forbidden and factored in with the price of the meal or drink. In almost all other parts of the world, the diner and drinker are expected to leave a tip after satisfactory service.

So, how much should you tip? It depends on service, total amount and other factors. The most general answer if from 15 to 20 percent of the bill. Your travel4seniors.com editor remembers car hopping at a Hot Shoppe in Philly way back as a college student. With all our running around the parking lot, we were lucky to get 10 percent. And not so lucky when the no-tip car drivers tossed their empty plates and trays at us as they raced away.

Food servers, both indoor and outdoor, work hard and deserve a tip. Sometimes a generous one can be a happy surprise. Recently, some very generous diners have been leaving 100 percent tips through the #TipTheBillChallenge, and bragging about it on social media. Hey, where were you back when I was slaving at the Hot Shoppe?
