In case you’re interested in renting skates at the Worcester Common Skating Outlet, keep in mind that you’ll need to give a $25 deposit for each pair of skates.
The deposit can be made either through a credit card [charged only if the skates are not returned] or with cash.
In addition, you can’t lend the skates to anyone else that day.
In fact, “SKATE RENTALS ARE FOR ONE SESSION ONLY. MANAGEMENT RESERVES THE RIGHT TO NOTIFY THE RENTOR TO RETURN SKATES AFTER ONE SESSION FOR USE BY OTHERS.”
Not sure how long a session is — I’m assuming it’s whenever the Zamboni needs to make a trip onto the ice.
You can find the rental agreement here.
