Some people have been asking why Manu's teacher has asked us to get a different bottle and tiffin. Two things, referral systems in India is very strong, schools ask students to buy stuff from particular shops and get a commission from shop owner, just like doctors get commission from pathology labs for sending patients. Second and most important thing is uniformity. I am sure Manu's teacher is not getting any commission from any shop. The reason was a combined tiffin and water bottle would eliminate the need of a school bag. Manu goes to play school and doesn't carry anything with him like books or stationery.
