People expecting to get free stuff

I genuinely hate when people show up to my workplace expecting to get something for free and insisting so so SO much hoping that I would change my mind.

I would love to give you a free drink but you haven't got anything else. You're just an idiot if you expect people to give you free stuff without purchasing anything else. Also you don't care that if I give you what you want I can lose my work? Are people even aware of that?

And then they start to say things like 'you must be new here I always get something for free' like what!? I've been working there for years and I have never seen your face around!

Or the worst thing 'I'm friends with the owners of this place. They always give me something for free'. Are you being serious? You think I'll fall for that?

And then if they don't get what they want then they complain? Like what in the world!? When did people became so desperate! A drink it's only a couple of dollars. Not even close to $10. I'm not gonna lose my job just because you're a disrespectful child-like person who doesn't accept a no as an answer!
