I hope the person is using thin set on the floor as well as back buttering.
That depends on the position and varies between thinset, back buttering, and thinset + back buttering. As it does with any tile laying anywhere.
IMHO the thinset put on the floor correctly and of the right thickness and freshness avoids the need for back buttering.
It may
Why not thin set a row of 8 tiles or better yet 2 rows and then lay them?
Because the substrate is somewhat reminiscent of a sponge it isn't remotely water proof so that area of thinset would not be useable. An area of one or two tiles works if the base is moderately absorbent, otherwise back buttering is used to maintain the correct consistency of the thinset.
There are good reasons why tiling is done the way it is in Thailand. As there are for the way it's done in the west
Do they have the plastic spacers to use in Thailand? most pros and me use them.. they come in all grout line widths.
Did you look at the pictures? The answer is there in almost every picture
Do you know that if you click a picture it usually gets a higher quality version?
However the longer answer is that Thai tile people all use spacers, most will use bamboo as it's abundant and free, while the plastic spacers will have a cost that in UK terms makes them £1.25 ($1.75) each or £65.00 ($84) for a bag of 50. So if they cost that much most pros and you would probably not use them, or at very least you would be thinking hard about the number of beers that they would be costing you
For them to have a similar relative cost to UK ones the would have to be priced at ฿9 per 1000 not the price they are.
