I'm surprised you would complain at so many restaurants Al, I mean that's not very 'British' now is it? Maybe CFH is right...

Seriously though, I've only ever had the balls to complain once in my life. I waited close to 2 hours for a steak at a local pub due to it being so busy. My complaint was born from the fact I'd drank 5 - 6 pints waiting so I felt all brave!

Got a full refund on meal though!
