night out part 2

I was standing at the bar when a girl walked up to me 'fancy buting me a drink ?' she said
'Sure' i replied 'as long as you let me choose the drink'

'Ok' she grinned 'but how do you know what i want?'

'well its kind of a talent i have, i can look a girl up and down and know just the drink that suits her best'

'ok' she said

so i looked her up and down
and turned to the barman
'one diet coke please mate'

Was she anorexic?
