Thats very true.
And here its common to shift blames. Whomever you call for repair, he will say Pehlay kissi nay kaam bara ghalat kia hua tha etc. etc.
Even in usa many things are either available on the online websites or on the websites of different manufacturers.
Last month i visit usa and visited home depot. i went there to find some adhesive for my shoe which broke down in the plane. I showed the picture to the home depot guy in adhesive section that i need something to glue my shoe's bottom with upper. They looked at me with strange eyes and said find something on amazone and order from there because they don't have some shoe adhesive 
Another guy told me to visit CVs and they have separate section of adhesives and i can find it from there. i went to CVs (which is actually a pharmacy) but didn't find it there either.
anyway, now i guess we have toooooooo much variety of the greases (not only in greases but in most of the things either these are cosmetic items or cooking oils or juices or clothes, or anything) is available out there and its not possible to find all items from one shop/website,
