4 of us on a night out at George Brays, Liverpool Rd, Islington. Yes, Brays was a rat hole but we were young and didn’t care. A wash and a meal and we were ready for a night out, “drop the trailer and we’ll take the Atki. unit” 
We’d had a ‘beverage’ or two and soon realised the Atki was a bad idea and we got on the tube.
Following morning…“where’s the Atki”? Nobody could remember where we’d left it, it took 4 of us until lunchtime to find it. 
When we got home old Fred Chappell went mad, he wasn’t at all pleased and threatened to sack the lot of us.
