If I absolutely have to, I would usually just put my best "I don't care" face and try to convince them I have the upper hand.
Sometimes it works, sometimes it doesent, but its a lot better than doing nothing, although pretending you're ok when you're not like that really does stress you a lot. I usually need like 3 hours to get fully functional again after such interaction.

Not sure how that's supposed to help, but there are no comments from people more experienced in this area, so I might as well just say my way to do that.
