what i usually do is wear earbuds and carry a plastic shopping bag and only been stopped once. walked past reception and towards lift and could hear them asking me where i was going as buds werent switched on then my arm was grabbed and they asked where i was going and answered that i had just been to the shop for things, they let me go and on way down put the items in the bag in my pocket and walked stright out..but now i work as a security in several hotels and you get to know the WG and who are their punters..sometimes i will tell the WG that i know who they are and wont be any problems.
