Cheers lads, I thought as much , I charged £20 outside, £30 inside and then I thought was that too much? but she has a cat which malts hair all over the place, so I get covered in hair, iv got to move chairs etc , heating is on FULL blast which seems to dry the bloody windows before iv even got my squeegee on the glass! hard work but lovely customer, makes a nice brew and never questions the price 👍
