Smell as signage

We need cleaner toilets or more shopping malls? Most of the time, public toilets announce their proximity by smell. Every Indian knows, this is nothing to be proud about. Therefore I like shopping malls, they gave the city (Mumbai) clean toilets. Males manage any how, but for females to find a clean toilet in public places is difficult. For the city with a population of 22 million, should we increase the number of toilets at regular intervals or increase the number of shopping malls? I am perplexed.

Assuming that free public toilets are difficult to maintain through tax payers money, now we see the toilets are paid and privatised (on contract). To increase footfall, privatised toilets are cleaner but persuade people with messages which seem rather funny. Instead of advertising for cleanliness, they promote AC toilet or deluxe toilets.
