In our drive thru when I worked at an ice cream shop, we had someone order a “Fruity Pebble shake” which was not something we could do. She had misinterpreted a sign that announced a new shake flavor (coffee) and another note at the bottom of the sign which advertised a “Fruity Pebble ice cream sandwich.” The amount of Fruity Pebbles that we had was extremely limited as we only used them for the sandwiches.
After we told her we could not make said shake, she tried to argue by saying the sign advertised one. We seemingly managed to convince her as she ordered everything else before again attempting to get a Fruity Pebble shake. She finally conceded and proceeded through the drive thru.
When she reached the window to pay and get her items, she again requested a Fruity Pebble shake. A girl calmly explained to her that we literally could not make one, she requested to speak with a manager.
For a bit of context about the establishment, it wasn’t a franchise or anything (there are like two of them, both owned by the same family). Most of the employees were a) in high school, b) recently graduated from high school, or c) over the age of forty. The older adults, however, only worked in the mornings, and she came during the later shift, meaning the oldest person working was in her early 20s.
When we said we had a supervisor, not a manager as it was a very small business, she continued to argue until the supervisor gave her the boss/owner’s number. Of course, nothing came out of it except lines on the sign to separate the advertisements.
