I love to go to my local all night bar on the weekends. I usually go with my good pal, and we stay there all night till around 4am. The best time to go is in the summer time months because the bar has a really good heating and air conditioning system in there. The air conditioning system makes for a really great night. We actually do not drink much while we are hanging out there all night. What we do is watch all the local bands that come in and play and just enjoy the central air conditioning system unit they have going. There is no smoking allowed in the bar except in one area that is closed off from the rest of the bar. So, the air quality in the place is totally clean and great along with the air conditioning where we hang out. I actually spoke with the manager of the bar about their central heating and air conditioning system and they told me that they invested a whole ton of cash into the central heating and air conditioning system in that place. I could not imagine that such a small time operation like a neighborhood bar would invest so much money into central heating and cooling! But, the true fact was, that the central heating and air conditioning system helped bring in more people on those hot and muggy summer nights. And in my opinion, it was a wonderful and sneaky business related trick. All I know, is that me and my pal love that central heating and air conditioning system!
