So I just went to the UPS store to drop off an Amazon return and I had the packing slip in there and the box all sealed up and the label affixed and all that like the directions said to. When I got there a guy at the counter (not the register) waves me over so I set it on the counter and the guy took it and asked if I wanted a receipt and I said no and then it was quiet for a moment so I left because I thought it was all fine with the label I shouldn't need to do anything but drop it off. But the guy who took the package stared at me the whole way out and now I'm freaking out. Did I do something wrong? Like, was I not supposed to just leave? I don't think he said anything but I had one earbud in and I was already anxious which makes my audio processing shit now I'm second guessing everything and just need someone not panicking to help me out here. Should I go back? Or was it fine? Has anyone done something like this before?

I'm sorry if this is a really dumb question but idk what do and it's already been a hell of a day anxiety wise so... Yeah any advice or experience would be helpful!
