Oh dear. I see I haven't given you enough info.
My customer owns a local car-hire business. He asked me to renew his fascias and guttering on his premises. When I turned up, I recognised that the secretary was someone whom I had known in my teenage years whilst a JW. Matter of fact she had a bit of a sweet spot for Yours Truly and would toss her head and wiggle her bum a lot back then, you know, the girly stuff that girly's used do sometimes.
Anyway, she recognised me too and was polite and friendly asking me about my family etc. It was during this time that she said that she couldn't make me any refreshments, so I just laughed and produced my Thermos.
Afterwards, I had a conversation with her boss and we had quite a laugh over the whole thing.
