Hurray.....

I had 4 beers yesterday.....

I have always wondered why bars charge the same (sometimes, more) for water/soda as they charge for a beer. 

Reason? If a patron consumes more water/ soda, he/she consumes less alcohol and vice versa.  Solution? Increase the price of water/ soda and goad him to drink beer. 

Similarly, my friend had noticed that most bars don't have clocks in a more visible location.

Reason? the bar patrons won't realize the time and would spend more time in the bar. The more the time the patrons spend, the more the business the bar gets.
