I thanked an ATM (that's a cashpoint you you and I) today. I didn't mean to do it of course, I wasn't really paying attention to the process and when a crisp tenner came out I said "Thank you!" as if I had been served by a real person.
I suppose it wouldn't have been a big deal except that there were five people queing behind me...

Did I explain that I was preoccupied? Make a joke and laugh it off with them? Did I fire off a bemused "I don't know what came over me then" look? No, I scurried back to my car with my head down, avoiding eye contact and probably making me look like even more of a twat.

That's the last time I visit Tesco in Rugby
