I'm taking my DC and 5 friends to the cinema tomorrow and going to a chain restaurant (think Pizza Express) afterwards. WIBU to bring my own cake to blow out the candles etc? I have made the specific cake my DC asked for so wouldn't want a generic restaurant one even if they did do it. We will be paying for food for a group of kids and a few adults, so it's not like we are trying to be cheap, we just want to use our own cake for blowing out the candles and singing happy birthday. Or am I being rude and presumptuous, and should instead stand outside the restaurant for the candle blowing-out?
