"Acetylene tanks should always be stored upright. While not particularly dangerous, placing a tank in a horizontal position can cause liquid acetone to get into the cylinder valve, causing the torch to operate erratically. Place it upright for at least 30 minutes before operating the torch. It is also very important not to withdraw acetylene from the tank at a rate of more than 1/7th of the normal full capacity of the cylinder. Again, this will cause acetone to be drawn into the cylinder valve."

The acetone separates out while the tanks are lating down, so then the raw acetone gets into the hoses, which will eat them away, to the point they rupture, then things can get pretty interesting...
He may be getting away with it for now, but it is a fair bet he will have it catch up with him... I can't say I have never done it, but it isn't the method of choice... Also, as mentioned it can let some of the liquid into the hoses and regulator, but that typically is more of an issue with propane, but can happen with a full bottle. The way the tanks are designed, the acetone can eascape when laying down, and acetone is what keeps the acetylene semi- stable.

What's really fun is when the acetone gets out of the torch- usually results in ***** of fire rolling around on what you are cutting. You should let the tank stand for 30-45 minutes before using if it is laid down.
Also, acetylene is only at about 250-300psi max, so the risk of the bottle taking off is a lot less than on oxy bottles.

Usually everyone is drunk, so nobody cares as long as the crawfish are
a.)not overcooked so they pinch easy and
b.) hot enough to diminish the buzz, another excuse to drink more, "my mouth was on fire"
