You're either thick or stubborn. Please explain how commandeering a wedding photographer to insist extended family get their portraits taken and then telling the DJ what songs to play despite the bride and groom wanting different music played isn't selfish, annoying or rude behaviour.

Did you just not read anything the OP wrote, including her multiple replies to you, describing how her parents insisted that everyone get a family portrait taken at her sister's wedding during the wedding party photo shoot? Again, in what way does that situation relate or compare to your experience of every single wedding you've ever been to having a photographer take a photo of every table? How is going around and snapping photos of seated tables the same as what OP has described? Please, I'll wait.
