“Choosing beggars” is someone who wants more or better than what they were offered. Criticizing the offering for flaws and problems is not.

IOW - I get a free chicken sandwich. I demand better toppings, a free drink and chips on the side. There’s a roast beef available, how come I didn’t get that? That’s a choosing beggar.

The chicken sandwich is undercooked, the bread is dry. That’s what’s happening here. Criticism.
