I can read moron and I have three experiences of overstay and I used to travel in and out of Thailand tens of dozens of times unlike the touristy, I have retired there experts. By the way, how do you think I post replies if I can't read?
Well according to your post they told YOU your 30 days allowed in Thailand started in London @Heathrow. If that's not hilarious I don't know what is 🤔
I don't believe some of the ridiculous comments on this. Obviously by people who have no idea of overstaying and with regard to a comment, it's not worth risking a five year ban for a one day overstay, that is the most stupid comment I've ever read.
