Quite a few, but hard to say how many now. Quite often in a guide will be listed as having a kitchen, but will end up being just a microwave and a sink, perhaps a refrigerator. No utensils. No pots, pans and dishes.
Sadly it is indeed to blame to some degree because of lazy, inconsiderate pilgrims not cleaning up after themselves, overflowing trash bins in the morning from the previous night's cooking activities, piles of dirty dishes and pans in the sink and tables not wiped down and cleaned.
I do not remember which albergue it was, but in the morning I went to the kitchen and it was just a total mess from the night before. Wine bottles lying everywhere, full trash bins and a sink full of dirty dishes and pans. About 4-5 of us spent the next 30 minutes or so cleaning the place up so the hospitalera wouldn't have to. I imagine the lazy pilgrims that made the mess were still snoring off their vino consumption from the night before.
As the expression goes, "can't have nothing nice".....
