Like in much of Asia - religion is taken exceptionally seriously in India so with that in mind - remember to always show the proper respect to religious buildings, shrines, images and people at prayer. When entering a temple or mosque - always remove your shoes (socks are okay!) and leave them at the door. Many Jain temples do not allow you to enter whilst wearing leather - so be conscious of that before getting dressed for the day! Women should dress modestly - covering legs and shoulders and men should always wear tops in public and avoid wearing beach shorts unless you are actually on the beach.
Polite conversation - especially that aimed at tourists, is quite different than you might be used to. It isn’t uncommon to be asked about your job and family on first acquaintance and you’ll find that many speak a very polite form of English and will address you as sir and madam - though try not to be taken aback - and feel free to be just as curious. Eating is a tricky subject if you remember only one simple rule - then let it be that, when eating with your hands - as is common practise throughout India - which you eat only with your right hand.
Tipping is widespread throughout India - though taxi drivers don’t generally expect a tip. Porters, however, do generally expect a tip of say at least Rs20 per bag. In restaurants - you can use your own initiative - if the service is good then tip anything between 5-10% of the bill - and less if you receive bad service.
