I stopped in because it was one of the few off-strip UPS Stores open on Sunday. When I arrived there were several people waiting outside at 5 minutes after open. I grabbed a coffee nearby and returned around 11:20 when an employee finally arrived and let the waiting patrons in, locking the door behind them (thanks to the patron who let me in when the door was locked to arriving customers). There wasn't much point in dropping my package off here on Sunday, as it wasn't remitted to UPS until Monday night.
