I am just 'wow' that you live on an island, i thought only Richard Branson did that!
If i had been you zippo i would have said to the lady who volunteered you "well, i would gladly help her but your big fat arse is in the way"
I would have said to the old lady " I will gladly help you as soon as the woman with the mouth bigger than her arse gets out the way"
I would have said to the bus driver "gtf up off your lazy arse, you sit down all day it will be good excersise to help her"
You did good anyway, fuck em. Glad you helped her, though.
