Do these people have write-only email or something?

Customer: OMG IT BORK!!!
Me: I can't connect. Is the external IP address right? Is the machine up and running?
Customer: ...
Me: Srsly, need to know this or I can't help you.
Customer: ...

Next day, in a new email:

Customer: OMG IT BORK!!!
Me: Still can't connect. Still need information.
Customer: ...


Of course, when they do reply you get exchanges like this:

Customer: IT BORK!
Me: Does it affect all records, or just some?
Customer: I don't know.
Me: Then why don't you find out you useless lump of shite?
Me: Do you have any examples?
Customer: Here, have one single example as a screenshot in a DocX file that you can't open because your workstations are a Mac netbook and a Linux desktop. I'm not going to include anything in the body of the email like the record ID or anything because I don't like giving you information.

At least it's Wednesday and I'm at home and don't have to wear trousers.
