I totally get that. But when one is giving advice and there is sufficient information that Thai offices have an expectation, then I think it's more prudent to offer the official regulations. But your point is well taken. Thanks.
I'm sure some people have anecdotal stories of exceptions being made but given that I live here now and am applying for an extension of stay based on age and adequate income I'm not going to mess that up because someone got a pass on Thai etiquette.
I had my appointment today. Relatively quick and easy! Thanks again for the info Tod! I will be posting a follow up question soon for next step at Immigration office. ;-)
