So some of you guys might know the UK has just brought in a law that all UK businesses that supply plastic bags with over 250 full time staff must charge for their carrier bags a minimum of 5p. 

Anyway, I thought because we are a big company we should be charging for carrier bags, 1500 customers later and we've made  a fortune on them, over £120 today from 6am to 4pm. I get a call from my district manager about 30 minutes after I leave asking why the tills from the morning shift were all 10-20 quid up, I couldn't explain why. SO I had to return to work and undergo an internal investigation for a few hours. That just finished a couple of hours ago and they've gotten to the cause, the trouble is what I did was against company policy and at the time I was afraid I was going to get demoted or sacked. 

Thank fully I didn't and the money has since been given to a respective charity which is nice. Our district manager is not happy and I was given a warning. It wasn't illegal though as many businesses charge for their bags even if it doesn't come under the new law.
<bot>: Always read your emails at work because if you don't you could fuck up like me and nearly loose your job by selling plastic bags.
