Here's my list of my first few jobs;
There was always too much rubbish so we had to take it turns to get in the bin and jump up and down on it so the lid would shut. We're talking about a huge industrial bin.
Ring people and ask them their BMI prior to appointments. For no real medical reason at all.
Arrive early and work unpaid for the first half hour so that the croissants would be cooked on time. No one ever questioned it.
Clean a big grease trap in a dishwasher which flooded the whole cafe knowing that the reason we had to mop for days straight was due to the company being too tight to pay someone to fix it.
