You seem to be the expert on everything so perhaps from where you sit Mr. Cox you can tell us majority what really happened....
That is a Spirit House - its not specific to budhism - and its a way of keeping the spirits in the building from causing problems - the logic goes that by taking care of the Spirit House, its a better and more happy place for the spirits to live in and thus look after the people in the main house, so long as its kept well stocked with food and water, looked after etc etc. Thai's believe all buildings contain spirits - hence you see spirit houses almost everywhere - they are sacred and should not be interfered with.
if you have Buddhist monks come in as an example, they will not do the ceromony at the spirit house - for that you need other people to officially open a spirit house and do the ceromony and also if one gets moved - you also need special people to come in and handle it, so as not to upset the spirits on the land/building.
Simply put - the Spirit House is an integral part of Thai culture and your best to allow them to do whatever they want concerning it - it will make your staff feel much much happier.

It's not a case of being an expert, it's just a case of taking an interest in the country and culture beyond the bar scene.
Mardhi obviously does too, very nicely put Mardhi
But we digress again ...
