Deliver Payments/Tips
Everyone wants to get paid, and as a Dallas wedding photographer, I can totally understand how a busy day means that envelopes get mislaid or forgotten. By delegating the final payments to a bridesmaid you know who has the envelopes and where they are so that you can enjoy the wedding without worrying if everyone will get paid out.
As a Dallas wedding photographer, I've seen weddings go smoothly, and I've seen utter chaos. Honestly, it was better for everyone when things went smoothly and one thing I've found in common was that all those brides made use of others within their wedding party so that they could focus on enjoying the day and focusing on the big tasks knowing that smaller things were taken care of.
