Recently we traveled to a country where it is not customary to tip. Here are some of our experiences.
One young hotel bell man went out of his way to get us a taxi, eventhough we were not customers of that hotel. We gave him a tip and he was a little stunned and embarrassed.
At one restaurant where we left some tip for excellent service, the server took the tip and had a discussion with the manager as to what to do with it.
At one impromtu musical performance someone gave a tip to the performer. She asked "is this gratuity?" When told it was, she practically jump for joy to share the news with the other musician.
And then we came back to the US.
