The woman brought her own food to the hen party and refused to eat with the rest of the group, but they never dreamed she would do it at the wedding.
Food is a big part of any wedding and it can be very stressful to arrange.
As well as being very costly, couples normally end up chasing friends for their orders weeks after the invites are sent out.
And then there is catering for anyone with special requirements - vegetarians, vegans and lots of different allergies.
But guests at one wedding were completely shocked when they spotted one of the bride's friends carrying a lunchbox filled with her own food at her special day.
