Oh my god she is so ignorant! When you pay for wedding catering you're not JUST paying for food, you're paying for a team of professional and experienced waiting staff, who will be on their feet all day, literally waiting on you and your guests hand and foot, keeping an eye on the drinks, serving canapes... etc etc. Not to mention you're paying for a (usually small) kitchen team to produce 70-100+ mostly identical meals, to come out hot, perfectly cooked, at around the same time. It takes an extraordinary amount of expertise and coordination. Even more difficult than a commercial/restaurant kitchen which is a feat in itself. It's absolutely nothing like just going out for a meal in a restaurant. Does she think the food just materialises?
Add this to her moaning about wedding dress prices and saying that she'd sooner buy something from a high street brand that was probably made in a sweat shop. The level of privilege is insane. The worst part is that there's no doubt she can afford all of it and some. A lot of people would dream to be able to have the kind of wedding an influencer can afford. I think she thinks her horror at these prices makes her relatable, that she's not lost touch with the pauper, but it just highlights her complete lack of perspective.
