Dude... the reason being has a lot to do with history itself and nothing to do with arabs and sheesha...
When a group is powerful, everyone wants to imitate.
Was not persian and arabic learnt by the elite of west India when Islamic empire was at its peak?
If Russia won the war, we'd all be speaking russian. Nothing great about it.
Furthermore, when Islam spread, the arab traders absorbed themselves in society, rather than imposing their culture on others. Arab traders married Indian (now Pakistani) women, they adopted what was not conflicting with religion, they adopted clothes, etc...
When the british came to India, it was very different.
Hope this answers your question...
PS. Arabs aren't allowed to go to bars in dubai, nor in UAE. Anyone who wants to go in must prove he's not a Muslim and get an alcohol permit.
