Ok so a big dog does a huge cartoon turd outside your tennement. One of your punters steps right in it and walks it through the entrance hall and wipes his mucky feet on your doormat.
a) Wait til the punter has gone until you discreetly nip out in your flimsy negligee to mop up the hall and dispose of said shitty doormat?
b) The same as above, but charge the punter more?
c) Leave the hall covered in shit for 3 days until someone else finally gives up and washes it and buy yourself a nice new doormat... but instead of throwing out the old shitty doormat, just plop the new one on top. Just so everyone can enjoy the smell of dog turd for a few more days?
If you answered c) you may be a loveable cockney wench... but you are STUPID! Do you hear me? Stupid!!! STUPID!!! STUUUUPPPPIIIIIIDDDD!
