I use a BAEC bag tag on my regalia bag - to distinguish it from dozens of identically similar receptacles after an indifferent but boozy FB at the Connaught Rooms.

On the other hand, when I check in my sky blue Samsonite suit case for a flight it is adorned with black and yellow hazard tape so that I may instantly grab the case from the carousels.

However, that, erm, "decoration" did not prevent a dogmatic and determined German at DUS last week from trying to insist that my bag was his. In the end, I was forced to get him to check his baggage receipt tag.

Not a single syllable of apology, though.
