Tea trouble

Tony: Cup of tea?

Me: No thanks. 

Tony: Why not? 

Me: It hasn't been tasting right recently. Not sure what's changed. 

Tony: But I just got new tea bags.

Me: Oh OK. What did you get? 

Tony: PG Tips.

Me: That's what you had before. 

Tony: Yeah, but I got these from Tescos. 

Cover story

Me: Where are you off to?

Tony: Off down the shop first for some milk, then working at 6.

Me: Working on a Tuesday? Unusual.

Tony: Yeah. Covering for one of the other lads. He's on holiday. 

Well, actually, he's working the night shift.

Me: You don't have a night shift.

Tony: Well, not 'night'. Evening really. He's working 3 till 9.

Me: ....how are you covering for him if he's working?

Tony: Oh, its cos one of the others is off as well.
