That's my dream guest. Come for a bite to eat, then feck off after an hour! 😆
Some people are different though. I went to a party of an ex colleague (Louise) some 20 years ago - just a 'pre-Christmas nibbles and snacks - and bring your own booze' thing, in early December. (She left my workplace 3-4 months earlier...) 40 people invited. 7.30pm til 'late.'
We got there at 7.35pm, and we were the first people there! Even by 9.00pm there was only 10 people! We were like
We had drunk the bottle of wine we took, and DH had 2 beers too. We ate some of the 'nibbles.' By 10pm there were 12 people there. She (the host) heard from someone she knew that most people would be along around 10.15pm to 10.30pm, when the pubs turfed people out.
By 10.30pm, still only 15 people, and none of them talking to me and DH as they didn't know us.The host and her partner were the only ones we knew! And we only knew him vaguely. We tried to chat to others but they weren't very talkative and only wanted to talk to people they knew!
We were so bored we called a taxi. It came within 10 minutes. (It came at 10.40pm.) We thanked her for inviting us, and went to get our coats. She frowned and said 'where are you going?' We said 'well..., home..' She said 'fucking hell it's only half ten! The party will be on til about 2am. A load more are coming at around 11pm' We said, 'yeah but we'll be off anyway... we've been here 3 hours now.' She said 'well fuck off then!' then turned her back on us.
I wonder if she was so rude and nasty to the people who couldn't be fucked to turn up til 11pm? Three and a half HOURS after the start time? Never saw her or spoke to her again. Nasty cow. Her friend who lived near her saw me in the shops shortly after, and said 'you missed a great party, leaving early like you did.' I said 'really? it started at 7.30pm and 25 of the 40 people hadn't got there by 10.30pm!'
She said 'they came not long after you went, and you missed loads of fun.' I said 'Louise was really rude when we said we were going, she told us to fuck off.' Louise's friend said 'can you blame her? She was really offended at you leaving early.' (So 20 minutes to 11 was 'early' when we had been there over 3 hours?!) 
I just walked off at that point, and never spoke to either of them again. Thankfully, I only saw this friend once or twice in passing and managed to avoid her, and never saw 'Louise'again!
tl;dr, some people get really snitty when you have the audacity to leave before they think you should! Really odd. YABU @doorss
