What’s wrong with this guy?

So lately this one particular guy has been asking me randomly and occasionally to buy or get him food snacks etc for instance few days back he asked me if I can get him some zaxbys during lunch bc he forgot his wallet at home, than recently he asked me if I can get him orange juice from the snack machine he supposedly would pay me back and I can just continue why he doing me like that?
