Umbrella confusion

For tonight's kickboxing class, we had a sub for our instructor since our regular instructor took the day off. The class was fine but it wasn't as intense and it just wasn't the same lol I really like my kickboxing instructor but he will come back next week haha

After kickboxng my coworker and I went to eat dinner at the small restaurant that sells seafood at the Shilin night market. I went there multiple times but they are pretty mean. They were rude like always but whatever. It was pouring outside and when we were about to leave, they tied the umbrellas up and put them on the table. I got confused as to which one was mine since mine was purple and there were 2 that looked the same plus there were other purple umbrellas. The guy with a table of 6 told me that those were their umbrellas but then I couldn't find mine. I just told the worker forget about it and I was about to leave but the worker told me stop in English and he was trying to figure out which was mine.

There were 7 umbrellas and there were only 6 people on the table. He gave me a purple one and said are you sure this is yours? I was embarrassed but I didn't even remember what mine looked like. I told him I don't remember the color but he just gave it to me and said in English "Remember your color." It was pretty embarrassing but the people on the table were rude. I tried to get their attention and they didn't even want to answer. Oh well...I guess now I know I really have to pay attention to what my umbrella looks like. I think I won't go back there for awhile lol
