Four young lads knocked on my door on the weekend and asked if they could wash my car for a bit of pocket money

Apparently, this was their idea, not their parents and they want to raise some money for some sweets and an electronic scooter

They wanted £20 but I offered them £30 if they did a good job

They finished after an hour and a half and knocked on the door to collect their money

I didn't open the door

I ignored them and they left with tears in their eyes

If you want to work in sales

Always negotiate your payment terms upfront
