A restaurant security guard who is also a waiter. Why? To protect and serve

Solid punchline. This would sell on a pun community.

You might be a little high, but you still did the funny.

Does this restaurant guard/waiter also serve weed?

Cuz I'm all in!

In reality it's just so he can afford rent. Pretty soon he'll need a 3rd job.

Wait staff is also trained to shield you with their bodies in case a food fight breaks out.

Not to worry. If you can get a step ladder for the security/waiter they can climb up and be as high as you are 😉
