Thank you captain obvious, but the person you are replying to didn't say they didn't understand the reasoning.
It's just really frustrating that there are entire classes of restaurants I can't eat at while on business trip or similar. They will not even just charge me an additional fee or charge me for 2 people (I've asked, and I know how it works/don't need handholding or explanations so they really just need to drop off the meat twice and change the grill once if it's too burnt), just typically get "no we can't do that, minimum 2 people" in response
