The visa on arrival allows you to remain in Thailand for 30 days

Assuming you arrive on the 16th June then you will have to leave on 15th July

there MAY be a grace period BY AIRPORT of 1 day

DO NOT rely on a 1 day grace period... leave on the date stamped in the passport, leaving after that date is OVERSTAY

the fine has been bumped to 500 p.d @ airport (??) -correct?

The maximum is still Baht 20K.

When you receive your 30-day entry permit, your passport will be stamped with the date that you must leave. Thai immigration does this as a courtesy for those who can't count.

There's no courtesy thing here, immi tells you the day you gotta go out and that's that. Nothing matters other than that date. This is one thing that Thailand does right

30 days is 30 days. They do consider 30th and 31st of a month as well as 28th or 29th February.

Any mistake made at BKK - airport can be corrected at BKK immigration office. They got a counter for that.

As has been said before on this thread, leave on or before the date stamped in your passport.

Simple.
