Whats your beer?

I was in a chinese restaurant and happened to overhear a neighbouring table's (which consisted of a family) drinks order. The conversation went like this:

Waiter: 'So what would you like to drink?'
Father: 'I'll have a beer, a tiger beer,'
Little girl: 'I'd like a drink!'
Waiter: 'So what would you like?'
Little girl: 'I'd like a beer too!'
Father: 'Oh really, what beer?'
Little girl: 'I'd like a Duff!'
