Any objections?

Say this to make sure a group of people are okay with a plan. This phrase is usually used if you’re pretty sure no one will have a problem.

Okay, so we’ll check out the boardwalk and then go for lunch. Any objections?

An "objection" is a point of disagreement. If someone asks you "Any objections?" and you disagree, you can say:

Yeah, actually I do have an objection. I think it's a waste of money.
