Finding a venue on a weekend can be tricky and remember, these things can cost money too, either at the expense of a organisers or a sponsor. I loved being able to provide food and drink (non-alcoholic too) as for me it’s an import part of what makes an event fun, social and memorable, but again it costs. I wouldn’t have been able to do it without the backing from my company, which not everyone has.
I completely understand your frustrations though, and if there isn’t an immediate solution I’d love to see if we can find one together! Feel free to DM me too
