I am invited to a birthday celebration tomorrow night for a 40th birthday for what is really an acquaintance of mine and i was invited through another friend. I hardly know her really but I said I would go as i like the restaurant and thought it would be a fun girls' night out. It is an all inclusive meal and drinks deal and costs about 60 pounds(I am in Dubai) plus taxi fares. AIBU to just turn up with a card or should i get a present too??
