I used to work as a tree seller in Bristol. The best flirting material was,

'Do you want lights with that?'

A rather bland comment but it was always retorted by 'It depends on who's going to put them up?' by the wife.

- Er, your husband, I replied.

'If he can!!!!' (he's standing right next to her)

- Ok, no lights? That'll be $70

'£70!!' Husband replies. 'Fucking rip off. Do you get lights with that?'

- Lights are extra.....and on we went.

I made £10 a tree btw
