Guys,
i have most of my domestic customers now on s.o's
if they object tell them you will collect payment by cheque and sling a s.a.e through the door with a slip when you clean them or you wont be able to clean theirs any more,the reason i give is not so i don't have to trail back because to be honest they don't give 2 f**** as long as their windows are clean,i say it's a security risk in this day and age to carry cash,most switch on to this.
cheers,
John.
