I beg to differ a bit, gadarene. the surety of whatever thrown at your need not be clean entirely. True the municipality is strict here, one good thing. but practicality of implementing it to the core is beyond control.
one thread in the QL forum also narrated an incident where a worker in KFC spitted at a snack box before hading it over to customer, coz she was unhappy with whatever!!!!!. . yak...

the idea is that these so called big joints should make and keep their employer happy, so would it be passed on to their customers.

irrespective of all these, the service (food and service) cannot be compromised, we are paying a price for the service we ought to get..
