Awwww, poor thing probably had a curry last night.
On days that I escape the office in time to get my express train home, I usually encounter a visually impaired man and his guide dog, as they get the train that leaves a minute before mine from the adjacent platform. (I can usually determine whether I am going to have to start running or miss that train, judging by how far ahead of me he is in the race up to the ticket gates).
Anyway, I always think the dog looks way too cheeky to be a guide dog and it DEFINITELY sniffed my bag when I went past him once. It totally makes eye contact with its tongue out like GO ON, PAT ME, FEED ME A SAUSAGE, which is kind of meant to be trained out of these guys.
