I'd really appreciate some advice please!

I've had a couple of quotes to do a tiling job in my bathroom.

One guy in particular seemed the most professional but there were a
couple of things he said which concerned me, one of which was a
technical issue.

I assumed he'd tile one day, and then return the next day (or later)
to do the grouting, once the tile adhesive had time to dry out.

However, he said he'd be able to do both tiling and grouting in one
day, and that it wouldn't make a noticable difference to the job.
I'm a bit suspicious, but admit that I'm not aware of tiling
techniques, so he could maybe be using a fast-set adhesive which
dries quick enough to allow grouting quickly?

Can anyone confirm this - is it possible, or more accurately,
recommended, to grout and tile the same day?

(On a slightly different note, he claims he's one of the guys the big
sheds subcontract to do their tiling, and he did come recommended
from a local tile warehouse)

I've seen a tiler working in B&Q. The noticable thing was the speed. He
tiled a kitchen display by the time I walked down the aisle and back but the
quality of the result was not what I would like.
I don't believe you can tile and grout wall tiles the same day.
Floor tiles maybe, as access is required to the room they tend to use fast
set adhesive but this has to be mixed from dry powder.
I asked a pro who has been tiling for 25+ years and he says no way can he
grout wall the same day, needs at least 24 hours in his opinion with ready
mixed (even pro stuff) wall tile adhesive. Possibly longer if the wall is
impervious.
