All due respect Nabbiex but why are you paying for Covid shots? I can't speak for Phuket but here in Hua Hin, the government hospital and Red Cross are both vaccinating for free and have done so since the very start of when vaccines became available. The Red Cross here even give you a choice of which vaccine you would prefer.
It's not "starting" to get out of hand, it's always been out of hand...!!! Thailand professes to be a 1st world country but as many long termers here know, it isn't!
Personally, if you are living here on an extension of stay, I would ensure I have one. Without one, it could create all sorts of problems at immigration when go for your extension renewal.
Not a complaint, just an observation as I chose to live here but, in my 10 years here I've found Thais to be a very selfish nation of people on the whole. There are exceptions but very few and far between.
