Manordeilo and Salem Hotels with Wi-Fi

Spent a very enjoyable evening with friends we hadn't seen for a long time. Unfortunately all through our meal overloud music was played causing the people at the next table to begin shouting at each other over the music causing the next table to shout over the music and the shouting from the first and so the ripple effect continued throughout the room resulting in a completely unnecessary loud environment. Why play loud music during a meal at all and why couldn't a member of staff ask whether the music was too loud or even whether customers wanted it at all during their meal?
