People bringing their own food to your house

[Catinthetwat]

Is it me or is this odd behaviour?

I have a friend who brings her own drinks to my house, e.g. a can of coke in her bag.

My in-laws do it too and I can't get my head around it. It's not like bringing a gift, they bring stuff for themselves. They bring stuff they like, rather than stuff we like, so it's not a gift. Though they do attempt to offer things around sometimes.

Am I missing something? I wonder if they don't want me to buy stuff for them, but I do obviously and then just end up with twice as much because they've brought their own!

My sister does this. She drinks a brand that I don't and as she visits sporadically she just brings some with her (if she's here all day) so she has something she enjoys to drink. I don't have a problem with it.

Really rude. As a guest one takes what one's host offers

If I'm going to someone's house for a meal, I'll generally offer to bring my own food, purely because I'm vegan and I know catering for vegans can be difficult if you're not sure what we do/dont eat and it generally avoids any awkwardness.

Yes - if you were going to a meal, or to a wedding or something, of course you do. But if you are popping in to a friends, then, in my world, that friend would want you to be comfortable, to enjoy your couple of hours, rather than 'politely' sipping at something you don't really like. As a good friend, I wouldn't want my host to have had to go to any trouble, going out and buying de-caff for me, if they don't normally drink it, but if I had 3 mugs of drinks with caffeine in, I wouldn't be able to settle to sleep that night and I would have a headache the next day. What kind of a person would want their friend to have to 'tolerate that when they can avoid it by carrying a few teabags in their handbag for just those occasions when you go somewhere where there aren't any?

Friends don’t mind, isn’t that one of the key points about friends? They aren’t arses?
