feeling vulnerable in CVS

The worst part of my Sunday was when I went to CVS for my booster shot and when I got there I took off my jacket and sweatshirt only to realize that I was wearing a long sleeve shirt so then I tried as hard as I could to roll up my sleeve all the way so that the lady could give me the jab near my shoulder but I was unable to get my sleeve that high so I, instead, had to remove my arm from my sleeve and, in the process, expose my chest and stomach to not only the woman giving me my shot, but also all of the patrons in CVS browsing shampoos and snacks and Tylenol which was awkward because then I was just sitting there, basically shirtless, making eye contact with CVS shoppers and employees while I was being poked with a needle. Otherwise it was a nice day.
