Focus on parking

Here is my Mono Monday Focus themed entry - a group of people concentrating on figuring out how to work one of the numerous parking meters in Harrogate.
Initially, the lady in the left of the picture had parked her car and was studying the meter and looking rather perplexed.
Then a second gentleman (in spectacles) arrived and started to help her. I looked back and noticed that the lady and gentleman had stepped back to allow a further two passers by to have a look at the problem. (That made four people concentrating on the matter!)
It occurred to me this might be a blip-worthy shot, so I hurriedly snapped the situation.

Thanks to Ellaphant for hosting the MM challenge.
