During meetings, I would describe one of my duties as their "tour guide" - making sure what they envision happens when they want and how they want....plus ensuring that anyone and everyone who was needed for any special event would know it was about to happen and would be at the ready.....FOB, photographer, etc...Me preparing is taliking to the bride/groom or customer to understand their vision and what important to them and their guests, then putting a solid plan together with room for flexibility. ill often do a ”through with” them so they can expect what’s going to happen and when.
