I would try to do a little investigation into the ownership and voting rights of the individual units. A developer who is acting as the juristic person (manager) may be holding title to the majority of units, using them as rentals. If this is the case, then the other owners are obviously in the minority and technically have no say in the management of their condo.
Take a walk down the street to the nearest 7-Eleven, grab a handful of 30 baht heat-and-eat sandwiches and stick them in the bar's beer cooler. That along with a cheap microwave and problem solved!
