I kind of feel like we would mind this encounter a bit less if this was all we had seen. The T shirt is cute and a bit dorky - so what, he is feeling affectionate to his new GF and maybe making a joke. They are out in the ocean, but that's more fun than a pool and why should they all hide? They're a group having fun on 4 July. Etc. It's when it comes on top of all the rest.
