The pug lady - Mopsdamen

This morning on my way to work I sat close to a lady with a small pug (mops in Swedish) in her lap on the underground. When I returned home also on the underground the same lady the same day sat down beside me with the same pug (mops). I said: Hello again! The lady replied: - Oh, I recognise you. The pug licked my hand and we started to talk. What are the likelihood of this happening the same day!?  Not so likely....
