Well, this week I think I was finally able to decide with near certainty what my worst stop is. It's a turnpike service station where you have to buzz yourself in and out through a gate. They get a ton of things every day and are only responsive about 50% of the time. Sometimes you have to buzz five times and they still don't respond, so you have to get out and run across the the truck stop to tell them in person to open the gate, whether it's getting in or leaving, then run back to the truck. Even if you ask them to get the gate for you as you're leaving, you still end up playing the buzzing game. I've often wasted 15 minutes on that one stop.
