Prison food?

Lunch place at the company serves vegetarian food only, it is ok most of the times, simple and cheap.
45 Rupies it's like 6 Swedish Krones but without any drinks, well you can get some water but as fellow colleagues don't drink it Im do not either. Still water is from 20 litres bottles so it should be safe drinking it. I usually bring a 50 cl water bottle from the hotel, which should be more.
