Apologies if this is a stupid question but UK tourists don't need a visa for a 27 day holiday do we? Or do we need to get a visa on arrival?

Just had a mail from Gov. uk. Entry to Thailand has now reverted back to 30 days! 🤔

I've read conflicting information, i'm coming from the U.S. and i would like to stay for 2 weeks, do i need to apply for any kind of visa or do i have an automatic entry if under 30 days?

I arrived into Bangkok and was stamped in.

My question is,

what type of visa is this ?

I have quite a few tourist visas in my passport, but I've been back to Canada in between. Most recently I came over with the multiple entry visa, and last I went to Laos for a new single entry. I am thinking to do a run to Ranong to get a 30 day entry, as I plan to leave the country to travel a bit at the end of those 30 days. But is it likely I will have problems without a visa? I have no 30 day entries this year, and can easily show a flight ticket and 20,000 baht.
