This guy with a dog asked me to buy him sausages for his dinner

He was obviously drunk and he had this pretty expensive breed of dog and I was just real with him like "Nah dude I'm skint myself". But I couldn't help but think "dude, you're drunk so you obviously had the money for sausages and spent it on shit so no" and he obviously has the apparatus to cook them which means he probably has his own place so why is he asking me for money -_-

I have sympathy for him because he's likely got an alcohol problem but considering the tells of his circumstances, I thought it was a bit rich. There are actual homeless people around here and if he has an address he get's benefits.
