Well, technically about 1.8 x 10^12 days. Without fine though, it's 7 days. If you don't need anything from immigration before your next exit, you can sort of just ignore it.
It highly depends, really visa doesn't matter much at all. You can get a drivers license if you meet the requirements to get a drivers license. You can get a pink id card in some places with little requirements and in some it's almost impossible.
A bank account is pretty easy, you can really open on any visa, but having an Ed helps. If you get a resident certificate, and a letter from you school you shouldn't have an issue, but it can be done without as well, but you might have to try multiple places and be persistent.
They have not made click 125i for a few years. They did 150i for about 2 years, but now I believe they only make the click 160i. The lead was the replacement for click 125i.
Usually there is a fee for the card or added benefits for the account.
If you are paying 7000 it's probably insurance. If you not on a long term visa, they are more willing to open account for tourist that pay for extra insurance.
In general, the Immigration issued ones are 30 days from the day they write it, which may not be the day you receive it. It will explicitly state it on it.
Really depends on your area. In general, tourist visa/exempt can get a drivers license as long as they can get the required documents. Mostly challenge for tourist in Bangkok and surrounding area is a resident certificate which requires a current 90 day report. Some other offices give them out like free candy.
do you question normal make you angry? Do you know this person motivation? Perhaps a Ph'D student doing his thesis on thai culture or something. I don't think it's any to get angry over or inappropriately stated.
Yes you can volunteer on any visa type. You can't work a volunteer job that would replace an actual job without a permit. There's a big difference.
If you want to go planet a tree or pickup trash with some group for the day, that's fine. You just can't have a full time regular role without permit.
Regarding making merit.... of course you can. If you would like, you can become a monk for a short while and, no that doesn't require a work permit either.
