Well said G&G!
Everybody has off days and sometimes being asked the same question by tens of people day in and day out gets tiresome, we call it being shop-blind or shop-deaf. I get the same way sometimes (in my job) and the ability to be aware of it is a difficult skill to acquire. On that same note, I also have a strong personality sometimes and will invariably clash with some people from time to time, nothing can be done about it except simply being courteous and polite.
Good on ya for responding G&G, shows me that you take alot of pride in your business! One day I'll head down and check out the place...
Cheers,
Shred.
