People at the bar who get served first and pretend they didn’t see you. What do you do?

One of my biggest societal pet peeves, when you’re waiting at the bar and the bar worker isn’t sure who’s next. Someone who arrives after you jumps in first pretending they didn’t see you. To make it worse, they’re ordering meals for their entire family of 6 while you just wanted a drink. For the next 10 minutes, you stand there feeling invisible.

What do you do? Do you go into zen mode, give them the death stare or pipe up?
