Not officially onboard credit... but I was on an maiden Transatlantic crossing... first revenue sailing... there were issues with some onboard amenities and service was hit or miss because of a new concept the cruise line was trying out. On the last night, they zero out all onboard beverage, specialty dining, and internet charges for everyone on the ship as an apology. I had $500 obc going into the sailing and that took care of my gift shop purchases.
