Aye, it sure is! Just been out to collect and had another one say the same thing....
Apparently, he asked her how much she paid, and when she said "about £6" (they're smallish terraces) he said "thats a bit much for this place isnt it?" so she called him cheeky and said she was perfectly happy!
To be honest, anyone charging any less than that wouldnt last... theyr deceptive, each house is quite easy but all together theyre a bl**dy hard days work!
