"would this even apply to the tourists?"

Think of it like this:
A tourist comes to Doha, are they allowed to
a)Wear a bikini around City centre?
b)Drink alcohol in the street
c)Exhibit PDA's in public
d)as a male, wander freely around a womens hairdressers?
e)Swear at the driver who has just cut him off
f)Smoke in a smoke free zone
or
g) None of the above

It matters not whether one is a tourist or not, the law of the land is the law of the land.
