And 'can you do the inside of my kitchen window', and then you've got to take your muddy, cat poo covered boots off and then clear all the bric-a-brac on their window sills; and then 'cos they look like a 'sweet old grandma', you don't charge them any extra; so they ask you to do it EVERY month and you've made a rod for your own back.
And then you have the other sort; the ones that look like 'sweet old granny'; but they're really wolves in sheeps clothing; they smile at you and say, 'That was quick', and you say to them, 'Yes, that's what Wor Lass says', and they just smile back and say, 'Yes'; blankly!
Despite my sarcasm, I do like the majority of my elderly customers though.
