I used the ham and bacon-slicing machines too when I worked at Victor Value. I was underage, and one day I cut my finger on the blade. The manager hustled me out of the shop, buying me a pint in a pub to try to keep it hush-hush (which I did). The pint was underage too!

Yep, that's the same spud machine. My mum threatened to sack me once for leaving the spuds in too long (they came out very small but there was no eyeing to do!)
