I've been going laundry at public laundromats on and off for years. I find that Launderland constantly gives the following:
Good clean results, IE: w/ your clothes.
-personnel on hand... although they don't always have English speaking skills.
(Since many customers also don't speak English AND the personnel seem to try to help it's all okay).
* The only downfall is that at times (usually in the evening), it can get pretty loud. Also, they used to provide news-papers to read. It helped class up the joint. (and it's of minimal cost to the owners).
