Floater

It is hot here. Very very hot. Today was 38c. Last night we went for pizza, after pizza we went for beer.
Life seems all good and normal, I went to the bar and ordered a pitcher of beer.
To my wide eyed surprise. The waitress asked me if I would like a 'Floater' in my beer... Most certainly not!
If you live in Brighton, a floater is a stray piece of floating effluent, a king Henry the third, a non flusher. What can this girl possibly mean?
Conversation..
Me "Can I have a pitcher of beer please?"
Waitress "sure, would you like a floater in that?
Me " Pardon me?"
Waitress " Where are you from? I love your accent?"
Me "I love the way you have your hair. Where are you from?"
Quite bored of the accent thing.
Me " You are going to have to explain this 'Floater' thing. I have quite a terrible picture in my head...
Waitress " would you like ice in your beer"
Me " I am not sure what is worse"
waitress " we put it in a bag"
Me " Good idea. I'd love a 'Floater' Thanks."
