No need to be offended and walk out like that. I think its better if you request it, file a complaint or let UConn athletics know about the situation. Showing you care about the situation can help you and others that are affected get a better result next time around. Im sure you not the only one. But there is just isn't enough like you to hurt Uconn's pockets so they can directly notice. Let your voice be heard and I'm sure they'll try to accommodate you.
Trust me, you are not the only one drowned out by market economics. It has happened to me for example: I have very long unusual arms, sorta disproportional to the rest of my body (runs in my family). Its hard for me to find a standard long sleeve dress shirt that accommodates my arm length that matches my neck size and chest width, gotta search around, try to use fitted clothing, and blah blah. Only some brands make the cut. Some stores don't even have anything I can feel comfortable with. Nonetheless, I let my voice be heard with a sales rep, the cashier, etc
