You are talking boŁŁoc@s again, we all read GASOs and you would risk death and an interview if you tried what you say. We also both know you're talking dribble as the imprest clerk is the wife of a muppet and any mischief would be quickly sorted......
What I've done in the past is change hotels if there's not enough room. Might I suggest you do a trick we support personnel do, ring the handling agent in advance and get your rooms sorted!!
