i'm sure this was discussed elsewhere but i am damned if i can find it
manchester airport two weeks ago, we were pretty sure we were close to the 20 kilos limit but i was very surprised to be told the first case was 24.7 kilos and they were going to charge me £25 for it!
remembering t'other thread i asked to see their calibration certificate and there was a definite buttock clenching behind the desk, the supervisor came over and told me their scales were better than mine so i asked why? show me the cert ( they didn't have one) the case was then re-weighed on the adjacent scale and miraculously came down to 20.5K
to show their authority they made us transfer half a kilo to our hand luggage, wonderful people....
