They were ‘practicing’ in Galleries Club when I was in there last year, near to where the computer desks are.
One of the Police Officers (without the mutt) asked me if he could put what appeared to be a small cardboard tube with ‘Training Aid’ printed on it behind my carry-on bag (not in it). I said by all means, so it was placed out of sight behind my bag.
A few minutes later the dog and handler appeared. The dog started to sniff around the area at the handler’s direction by pointing. The dog sniffed at me then my bag and just froze.
The handler gave the dog a fuss and threw a ball a few feet away which the dog chased. The other officer recovered the ‘item’ and thanked me for my assistance.
I said that I was pleased to be of help to them.
For info, at no time that I could see did the dog sniff around the food areas etc.
