You’re invited to a BBQ and told you have to bring some meat and some drinks - what is your reaction?

Almost every BBQ I go to is bring your own food and drink. That way everyone can eat what they want, no-one is left not liking anything on offer, any allergies can be avoided (either segregate the BBQ or cook in a sensible order). It also prevents the hosts from buying the wrong amount of food; too little would be a disaster, too much would leave them more out of pocket than they had to be. Personally I typically take a few burgers and a few rolls, maybe some kebab skewers or sausages; less than £10 worth. And typically spend a lot more than that on booze so it's not exactly a crippling expense. I'd feel bad about not contributing if the host was laying everything on for everyone, and I would buy them a bottle of wine or something as a thanks.
