We had an amusing experience at Sticky Fingers in Myrtle Beach. I asked the server - who looked to be a young teen - for coffee with cream. She brought the coffee but not the cream. When I asked for the cream, she replied: "You'll have to wait because I have several other tables to wait on right now".
I was able to flag the manager and explain that someone needed to take her aside and quietly explain her error. I didn't want him to do that while I was sitting there with my husband but wanted it done in a way that didn't embarass her.
The manager brought the cream to me and when the waitress came back to the table, it was obvious that someone had instructed her to handle the situation differently from what she had done. She did a fine job from there on throughout our meal.
Because my husband and I operated a small restaurant in central New York, we know the hard work that goes into restaurant work. Almost without exception, we tip well.
