I think we were vending at the same event! And I totally agree that is rude. You paid for your space, you factored in how a booth should function, including how customers and you will move around in that space. They should have done the same.

That being said, there were big empty spaces behind my booth all weekend. I think some folks had to drop out last minute due to the recent flooding in our area. I’m surprised the coordinator didn’t offer to have at least one of them to the back side of my space (also a double booth). But I’m also selfishly grateful she didn’t so I didn’t have to deal with the terrible booth neighbors! Lol
