@AkbarGr8 when the buyer know the market closing time they will adjust their shopping habits.
i read a very highly annoying post over social media though true. It stated that Beggers are more blessed with income for their habit of punctuality, as compared to any shopkeeper. A begger is at traffic light outside bakeries, near vegetable fruit markets, morning restaurant & near schools spot on 7.30 am begging car to car, table to table collecting his dough. while the shop keepers are cursed as they tend not to open shutters before zuhar azaan 12 noon onwards.
there is a famous store chain which is open at 7.30 am 7 days a week, close down at 11. 00 pm. Their morning schedule has multiplied the business, for ladies with drivers do the fresh grocery shopping after school drop-off in single trip. that's 1 basic example, there are many business places i know of which are open at 8 am, across lahore / pindi / karachi and they close down at esha azaan.
am in favor of early open early closure, people will adapt to schedules.
