When I was a child in Glasgow all fizzy drinks of the soda variety were called Ginger, hence the following exchange.

Haw ther mister can a hae a bottle o Ginger?
Aye son, whit flavour dae ye want?

Another great Glaswegian anomoly is the habit of calling male strangers Jimmy. Thus

Hello ther' Jimmy, whit's yer name?

Funny old world isn't it?
