As i said before, he came and spouted an advert. all fine and well, except he's already spoken to the top guy here, and didn't say anything we'd wanna hear. He couldn't be specific about discounts, because he probably doesn't do any and hopes his prices seem good to us.
Now if you come somewhere like this more than once, you will be made welcome. However, if someone came trolling, what, would we say "hi, how you doing? spam away mate"? of course not. so when someone drops us the digital equvalent of a cheap mass-produced and delivered pamphlet through the door, we're hardly gonna ask if he has any more!
So, if you wanna come back and chat mate, thats cool, but i suspect we'll not see you again.
