Day 81: I Buy Wine In Marks And Spencer

I am buying wine. The young man on the till picks up the bottle, looks at it, then looks at me.

Man on Till: Linda? (Waves bottle of wine at supervisor lady in glasses.)

She glances at me.

Linda: Yes, she's fine, love.
Me: (A slight thrill passes through me.) Were you just checking to see if I was over 21?
Linda: It's the young ones. They can't always tell, you see.
Me: What, that I'm over 21?
Him: I can't always tell, you see. I'm eighteen. You get past a certain point ...
Me: ... what, twenty?
Him: It's obvious now I look, though.
Linda: Yes love, you should look you know, you will be able to tell.
Me: Come on. You could at least PRETEND. For my sake.
Linda: I could, I suppose, but ...
Him: ...Cashback?
