Here’s my take…

Hotel air conditioners feel like perfect air conditioning. Likely due in part to hotel rooms being a small space, usually limited to one outside window, and they are usually good sized units so they will cool it very fast and effectively. Also the rooms are usually warm when you first enter, and so you turn on the A/C and immediately feel the room getting colder.

Similarly, McDonald’s pop is essentially perfect. McDonald’s arguably strives for consistency above all else, so you know that a Sprite from any location will be the perfect mix, the exact right about of carbonation, perfectly chilled with jus the right amount of ice. It will even have their specific large diameter straw to ensure the ideal flow rate when you drink.

They ozonate the rooms to kill all the germs and creepy crawly stuff and it's similar enough (2 oxygens in CO2) to how they fizz the carbonated water in the sprite. The sprite is light enough in taste, vs coke or pepsi, that you notice it more. That's my guess but if I'm wrong, please correct me.

Nobody tell him
