I'm going to offer a friend a ticket to a place but have it be a lesser ticket than my own.
Why are you offering a cheap ticket to your friend?
I'm just trying to be nice
While it is nice of you to want to help your friend out, you might consider just giving them the money you would pay for the cheaper ticket so they can use it to buy a better ticket like yours if they want to. It's kind to offer to do something for people, but it's rude to be obviously cheap with your generosity.
I will do as I please. Also, I will charge you.
You can't charge me, and you shouldn't give your friend a ticket if it is going to be lesser than yours. You should both use the same level ticket while you travel, and I think that would make you a much better friend.
