This situation is just awkward all around – there’s no way to put a positive spin on it. We’re not sure who should feel more embarrassed at the moment – the guy who’d been outed, or the girl who’s on a date with a guy that’s just using her as a cover. Or is he? We don’t really have enough information to really know what’s going on.
All we know is that it’s an awkward situation. The waiter must have felt pretty humiliated at the moment as well, which is why he spoke out. Did you ever go out with someone who just used you as a beard? I always thought this kind of thing only happened in the movies.
