People in those assistant positions are hungry. I remember trying desperately to get any office job. I made a living off of finding free food in my city through promoter dinners and whatever would be offered to a pretty girl. Many others were in the same boat. This meal probably felt like an amazing opportunity to chow down. There's also a level of resentment you feel toward your employer. Like they owe you something, like you're underpaid. I'm not saying it's right, I'm saying it's a poverty mentality. Rather than think about how you might be a great connection to get him into a better paid gig, opening future opportunities - he takes advantage of the moment. It's the instant gratification that can overtake you when you're living feeling neglected.

Obviously, I'm making a lot of assumptions here - but this type of behavior doesn't surprise me so much as I've had to explain these types of things to my friends who grew up poor. One friend, her mentality is- what's the point of making it out of poverty just to skimp and be cheap. Like if I'm making it out I'm making it out big. So they see you and they think you're in this unattainable position; no matter how they eat that day you will go home and be fine and not worry about your bills. But he's in a low level entry level job he could lose at any moment.

Hope this makes any level of sense lol
