Today I learnt the following important lessons.

1 - Where the Sugar-free jams and chocolates are kept.
2 - How to do reduced pricing on the till - hardly any mistakes today! I'm getting better!
3 - The code to get access to the staff only bit.
4 - Possibly the most important part - how to get the clock up on the till, telling me how much longer until I get to go home.

Baby steps people, baby steps!
