Do i really need Evening food?!?!

I’m a South African getting married in Scotland to my Scottish fiancé and I can’t get my head around evening food?!?


We have canapés going out at 2:30pm. Our reception dinner meal and dessert for our day guests is at 5:30pm. Evening guests (20 of them) arrive at 7:30pm and cake cutting is at 8pm for all the guests. Personally, I think feeding evening guests that late doesn’t make sense to me? I’m sure they’ve had tea if they are arriving at 7:30pm.I was thinking just get Wraps and pies from Costco and lay a few out maybe 100(as the wraps are cut in half) but my fiancé is persistent that it’s not enough food or it comes off very cheap not to feed them a meal.
I need some guidance on this because I can’t wrap my head around it at all…
