On an initial shipment inquiry/quote at this location (Cosmopolitan Las Vegas) there was no outbound shipment fee, but when I came back later to ship my package the clerk tried to add a $10 fee (really ridiculous considering the shipping itself was only around $6). When I told her that there was no fee applied previously, she said there should always be a fee and there was nothing she could do; when I asked to talk to a manager, the clerk said none was available and claimed she had no idea who I talked to earlier.
If they had been truthful in the first place I would have planned to go to an off-Strip location (especially since there are several with just minor detours on the way to the airport), but because I scheduled my day based on a quick dropoff here this wound up being a huge inconvenience. I feel like it might even have been an attempted bait-and-switch, which really leaves a bad taste.
