Receiving email inquiries from customers who don't use decent spelling and grammar. I'm not demanding perfection (I may dream of perfection, but I won't demand it). But I think I can reasonably request that a question asked of me be comprehensible. Half of the inquiry that is prompting this post was one run-on sentence, including some abbreviations that I think the writer may have made up. It took a while just to figure out how to phrase my response. On another note, the customer did not include her full name in the message, nor where she's from (which makes it difficult for me to address her professionally, or direct her to possible alternate resources).
