Can you tell from this introduction that this is not always the case?
When Mr. Spaniel and I visited our venue for the first time, the site coordinator told us that the room that we were most interested in was available with a 100-person minimum. It was usually a 150-person minimum, but since our wedding was in the off-season, they could work with us. Great! We were hoping for 130 people at the time (with a 150-person guest list), so that would suit us just fine. She also told us that a champagne toast would be provided "as our gift to you." Nice! We really wanted a champagne toast, and were happy to receive it for no additional cost.
When I returned to the venue with Papa Spaniel, the coordinator had not relayed to the rest of the staff that the minimum was being waived (or reduced). We weren't willing to spend nearly $125 per person when said person was not in attendance, so it was a do-or-die kind of clause: if they couldn't meet our requirements, we weren't having our wedding there. Luckily, we received a call from the coordinatormisunderstanding, of course we'll honor... Awesome! Problem solved.
Luckily, Mr. Spaniel took over for me and mentioned the champagne toast at the details meeting. As it turns out, the open bar serves champagne (which I did not realize before), and a glass of champagne with a strawberry garnish will be handed to guests after the ceremony on their way into the reception (the "gift" about which the coordinator was referring). People are welcome to toast with whatever they would like to drink. This works for me! Since a lot of people don't like champagne anyway, people can toast with whatever is in their glass (and that can be champagne if they want it to be).
Did you run into any of these kinds of contractual issues? Were you as big a chicken as I was about any of them? ;)
