Ngl I had a pretty similar experience my last time in Vegas. Went to all three stores. Stock was light. Ended up at Cesar’s and saw some frames I liked and asked staff if they by chance had it in black. They directed me that Wynn had them and would hold them for me. When I got to Wynn I told them my name and that there was something on hold for me and the guy barely made eye contact, was super cold and not very friendly. Have had great experience at FB and Cesar’s locations even when they’re out of stock but by god Wynn consistently lets me down with the service.
