So a customer came to see me to discuss yet more changes they wanted to make.
Customer: "See here on the final check out it's saying Tax 7%?"
Me: "So who changed the values?"
Customer: "I, I don't think we have?"
Me: "OK lets go Taxes--->Tax rates, change to UK 20%"
Customer: "Ooh was it that easy?"
Me: "Yep, but I'm still billing you for it."
Customer: "But? But?"
Me: "Hey, I knew how to do it and you didn't that's why you pay me."
