Is there really any need?
I need help with something techie, so I contact techie people. Next day techie people respond, suggesting I should give them a ring to discuss further details, or to go to other techies who can help me out in different way. I don't like calling about techie stuff, so decide to drop by instead with said techie object.
Is there really any need for non techie enquiry person to give me bad attitude for dropping by instead of calling? Really? Didn't think so. You dis-made my day. Thanks.
