I'm not sure if there is a Guiness Book of World Records category for tumble drier purchase, but if there is I want to submit an entry.
Our tumble drier broke last night. We've had it 21 years and it goes and fails on us. Actually the drier itself is fine, but the bit which makes it stop was broken. We found this out after it had tumbled a bunch of clothes for three hours. Ooops.
Anyhoo, having been told in a couple of shops that they didn't have what we wanted (I reckon the bigger the store the less chance of it actually having the thing you went in for) we found a place that did. So we swooped. Into the shop, pick it up, take it to the till, pay for it, less than five minutes.
And it works. And it stops. Wonderful.
