BGL: You would?
Me: Why not?
BGL: Um... OK. What sort of card is it?
Me: ...a debit card?

Me: A [name of bank] debit card?
[more silence]
Me: Uh... [brand name of card]?
BGL: Ah! Could I have the long number on your card?
Me: [gives it]
BGL: Start date?
Me: [gives it]
BGL: Expiry date?
Me: [gives it]
BGL: Start date?
Me: I just gave you it.
BGL: Sorry, issue number?
Me: [gives it]
BGL: [long pause] I'm sorry, the card isn't registering. Can I have the long number again?
Me: [gives it, and all the other details above, again]
BGL: No, it's still not registering. Do you have another card?
Me: Look, I have direct debit on my British Gas account....
BGL: Oh, you do? (pause) Oh yes, you do. Right, I'll just debit your account then.
Me: [says nothing, but contemplates switching to Southern Gas and Electric]
