Mate, if you work on retail or a Supermarket 1.50 is a heck of a raise. They will look for every reason on your performance to not give you a raise and the closer you get to the max hourly rate is less the amounts of a raise. They even stop right before it gets to the limit.
A ~$6.50/month raise is a pittance by anyone's standards.
A $1.50/hour raise is decent by most people's standards, as that works out to about ~$3000/year for a full time employee, vs the $78/year raise $1.50/week gets you.
That said, $1.50/week is likely a typo/mistake. An extreme few number of places, if any, are going to give someone a raise that amounts to a few cents an hour.
50 plus years ago a few cent raise would have meant something. In the world in which we now live, not so much.
And THAT said. I bought 2 bananas for $.22 tonight. That very well might be the first time since the last millennium that my total at a counter was less than a dollar.
Why would you waste gas just to buy 2 bananas? That seems a little...you know
