KYGMSY,
I believe that you need to look up to your belly, because if they ask you those type of questions is because there were previous incidents with you or with your mates over there;
If you want to play goods will to aviation that's fine, if you are being blamed for someone else I would suggest to grab the bull by the horns and show some professionalism for a change.
Do not take it personnal, but I hate when people start to criticise others as an excuse for not doing the job.
I forgot to present myself, I am Mach.99 and
I feel the need for speeeed!
Cheers!
