To think it's rude not to wait for guests..?

My parents invited us for Easter lunch. They didn't really give an exact time said around 5-6. Admittedly we got there just after 6.. they had already started, and almost finished eating.
They do this all the time? I can't imagine inviting them and if they were late just start eating without them.
AIBU to think it's rude not to wait? Or is that me expecting too much?

TBH, '5pm to 6pm' is a stupidly large 'window' to tell people to arrive. If they intended to start cooking at say 4.45pm-5pm-ish and it was ready for 5.30pm, (which it sounds like - as they were done eating by 6pm,) then they should have made it more clear.

Their behaviour was passive aggressive and childish. And manipulative. And designed to make you feel shit/guilty/small.

YANBU @easterbunnyz If they had wanted you there by 5pm to 5.15pm (which they obviously did!) they should have said. You're not psychic FFS!

I think the time given was too vague. If someone said to me between 5 and 6, I'd think time wasn't particularly an issue and might arrive just after 6. I think it was rude of them to start without you. As someone else said, why didn't they give you a ring if they were getting concerned about the time?
