It happened to the whole family. We drove about an hour from a very small logging town to Sacramento and went to the mall. We stopped at a nice jewelry store so my husband could have his watchband repaired.
Yes, we were dressed casually, but not slovenly, jeans, shirts, coats, all clean and neat. The saleslady (dressed to the nines) took his watch by a tiny corner with two fingers, acting like it was contaminated, looked us up and down -took the watch in back and came back and suggested we go to Walmart for the part, that they didn't have it.
In my youth I allowed people like that to make me feel bad about myself. I wouldn't stand for it today - but 30 years ago, she managed to make me feel small and dirty.
Ironically, we had money in our pockets to spend but we sure didn't spend it there.
