We try to catch as many bad t-shirts as we can but unfortunately we don't see everything. Did the CM/Manager give you attitude or anything when you did get them?
I've never heard of the alcohol t-shirt rule and have seen too many drunk people to count while I'm clearing the park.
I'm sorry, I should have elaborated a bit and I apologize in advance that I'm about to sidetrack this topic a bit. You're right, the cast at the turnstiles can't see everything and you know why that is? Because Disney cheaps out on labor and makes one CM work multiple turnstiles. You can't actually look at people's tshirts when there are thousands coming at you with questions, inability to "stick it in and put your finger on it," strollers, wheelchairs, complaints, it's chaos. I get that, and I'm sure there are some front entrance people who would laugh or just simply, for minimum wage(CPs), don't want to cause a confrontation with a guest when there are thousands to be let into the park.
I have been in that situation myself, as I actually saw someone get off my ferryboat at opening with the F word on it at MK. But there was a ferryboat of 600 waiting to come in and all I can do is follow the guy to turnstiles to point it out to front entrance, who actually has the power to do something about it. Sadly, I had to take the option of letting it go, but I doubt, given the way the shirt was worded, that anyone saw it at the turnstiles.
Having said all that, the biggest issue I have is the ONLY front line CMs who have the power to ask a guest to turn a shirt inside out or threaten to throw them out are main entrance ops. Any other CM, from merch to security has to call a manager. So now the % of CMs who aren't going to DO anything about it increases. Thankfully the day I was in EPCOT, I was a guest so I talked to the German merch CM who got her manager. The little brat ended up getting a free t-shirt. It used to be they just made you turn it inside out. I was actually mad about that, but whatever, at least he's not working around with on his shirt!
What I find interesting though is it's a different component when you have alcohol involved. Now suddenly service can be refused because of beer on a shirt. Makes no sense to me, but then again, a LOT of things don't make sense about Disney.
edit: and no, I didn't get any lip from the CM or manager, but I can't believe the kid made it all the way into world showcase to Germany with no one saying anything about it, guest or cast! Why? Because cast are not empowered to do anything without a manager, so most simply aren't going to bother, and it makes me both sad and angry at the same time.
