I’m sure it was meant to be a joke. I’m under a different office. They never complete any forms for you as that forms part of their VIP service and includes an appointment time which is, of course, not normally available.
You need to have a word with my Visa Agent. The majority of her long term (returning) customers are Brits. Lack of cash is one problem, the work (and type of work) that some of them do is another. Finally, when they get in trouble, they bring her all their paperwork. Although written in English, she has to read it to them and explain what they need to do. Literacy is not their strong point.
Good thinking! I too would go with this. I’m assuming the OP has counted day of arrival as day one? If do nothing the 500 baht per day overstay fine is normally waived for the first day. However, passport would still be stamped in red as ‘overstay’.
