You are right and the GP is wrong. When I worked for near minimum wage I was very conscious of exactly what I would get in each week's paypacket. Either a couple of extra hours or a small payrise (eg. 40c per hour for being kitchen trained) were a big deal to me.

If you are making say $380 a week, you might have fixed costs of $200-$250 a week. Other costs, maybe $60-100, which are difficult to cut without making your life much worse. And the constant chance of an unlucky break which will cost you $300-1000 and need to be paid straight away.

A small payrise can mean the difference between having $20 left over for everything nonessential, and having $50 - 2.5 times as much. Or the difference between having $30 and having nothing at all. Or the difference between ending the week with slightly more than you started, or with slightly less.
