Had you ever said anything aboutnot being able to eat fish and chips now you have diabetes? Is it possible tht work colleagues wanted to et fish and chips and decided not to tell you, becuae you'd said you couldnt eat fish and chips? It's a shame you've been left out, but you need to find out birthday etiquetter in your office. If you're new, perhaps there is an ongoing birthday fund. In about 2007, I worked somewhere where everyone paid, I think £2 per week for tea, coffee and milk supplies, which left enough extra to buy cakes on Friday nearest to anyone's birthday.
