please remember, your cashier is human too, the machines do sometimes go wrong, we do not have a magic wand to right all wrongs, and degrading us by telling us we are "disgusting" because you dislike the colour of our hair or our tattoos is a massive reflection of what a giant cockwomble you are.
Also, a thankyou to everyone who has taken the time to be friendly, who has understood and been patient when things go wrong, who has thanked us when we help you.
Finally, an extra special mention to those wonderful amazing customers, who take the time to be extra kind to us when it is obvious something has gone wrong, and who stick up for us when the first group appear.
I'm sorry that those in the latter two groups end up overshadowed by the former.
