I've never understood why it's so important to talk then and there as opposed to moving somewhere else that is a bit quieter and less likely to get bumped into or shouted at. I've always wanted to grab their phone and say something like, "Ohhh baby, that feels soo good, don't stop, it's even hotter with people listening to us and that kinky boss of yours". It should get them to move to wherever they were headed without looking back.
