There is something floating in your drink. Do you pour it all out, fish it out, or just ignore it and drink?!
Answers: Depends what it is. If it's an olive in a martini I'd keep it. If it's a spider in orange juice I'd send it back.
If you're at home, pour it out, rinse out the glass and then refill it. If you're in a restaurant, point it out to the server and they'll bring you a fresh one.
I find it really off-putting, I get a new drink.
Totally depends on what it is. If it's just a little speck of something, I would fish it out with a spoon. If it's a big chunk of food or something that has disintegrated in my drink, I'd get a new glass and drink.
I always pour it out and get a new glass. Or, if it doesn't look totally gross, my husband will usually drink it.
