As a customer, I expect decent and polite service; and should the response to my exasperated; "How can I get a little service?" be
"Go to a little Church!" then you just lost a client!

However, I fully realise that starting businesses can have horrible blundering glitches, screwed up orders, unanswered queries, curt replies etc. So I don't get too melodramatic unless there is lots of my money involved. Everyone deserves a chance to improve (That's why erasers are put on pencils) within a reasonable adjusting period.

But, once the 'newbie' finally gets established, the Gremlins are conquered, his/her store is opened, business picks up, then I expect consistant, excellent service. Should this still not be forthcoming, well, there are other businesses.....
