MUM - THE BUS PASS SHOT

Not wanting Mum to have to pay £5.00 in a photo-booth, I offered to take a picture which would be suitable for her travel pass.
We then went into a high street photo store and asked them to print the picture in a small format.
They did this for £5.99.
Mind you , the guy offered to take the picture himself for £6.99.
Mmm...tricky choice.
Do I bop him on the nose or not?
