... no matter how many times I say, "I'm not interested, thanks" !?!!
Just had a farkin salesman stuck to my doorstep after repeating "I'm not interested, thanks" about 10 times.
He didn't get the hint until I started to shut the door on him!
Stupid bloke - I rekon there should be a rule that means they can't stay if you declare you aren't interested in their product or whatever instead of keep rattling off their prepared speech and ignoring whatever you say!
