When she reasonably offered to return the pop they refused. They are at fault.

That would be like trying to return a cigarette after you smoked it. Once the soda leaves the dispenser machine, it's pretty damn hard to return it to a re-dispensabe position.

You are correct, but since they didn't post a price and she had previously purchased the soda for a dollar they should have charged her a dollar and told her in the future that it would be $3.80.

“Once the soda leaves the dispenser machine, it’s pretty damn hard to return it to a re-dispensabe position.”

She could still return it. Here is how it works: She gives them the cup. They go to the sink and dump the soda down the drain. They give her cup back. That is how you return soda. (Don’t try to talk about the cost of the soda unless you want to look like a fool.)

It is the correct solution: She did not get the soda below what the manager wanted to charge, and the manager was not allowed to make up a new price and force her to pay it without forewarning.
