Yep. I just spent a month in Thailand. She picked me up at the airport and dropped me off at the airport. She had enough English to make it work and she really increased her language capacity but as you said, when we got around her family it was all Thai language and I couldn't keep up. She would stop and include me the best she could but played out the way you said. I am giving her my loyalty unless something changes. She never asked me for a dime and I forced her to take $10,000 on the last day.
when I arrived in Phuket I had to have prearrange prepaid RT-PCR Test and SHA-Plus Hotel reservation for the 1st night which you were ushered off by the taxi right after swab. The hotel will be emailed your result so you know when you are free to roam. Google Thai Pass and it gives the list of eveything you need to do. Have it all in a folder because every airport enroute will ask you for all requirements "when" they see your destination is Thailand.
