We could stay up drinking until morning, all the while arguing about the differences (if any) between Porter and Stout, but the only point of agreement might be this.
Entire quickly became popular as the workingman’s pint of choice, and as several historians seem to think, became known as “porter” because it was a particular favorite of the porters who labored at the local markets and also delivered the product to the pubs.
Historically, a porter is a person employed to carry burdens, as at a market. In the UK, what makes a "market pub" noteworthy is its exception with respect to allowable opening hours.
In Indiana, the rules are uniformly favorable. Any bar can be a "market bar," though not many do.
Sunday through Saturday, the legal hours for the dispensing of alcoholic beverages are 7:00AM to 3:00AM (IC 7.1-3-1-14).
Retailer permittees may allow the consumption of alcoholic beverages for a period of thirty minutes after the legal dispensing hours only if the alcoholic beverages to be consumed were purchased and received by the consumer before the applicable times (see above hours) to stop the dispensing of alcoholic beverages. After this thirty minute period, all containers that have previously had alcoholic beverages in them must be cleared from the tables, counters, bars, etc. (905 IAC 1-10-1)
Markets and their laboring porters. Porter as an ale brewed by the likes of George Washington. New Albany once had a market on ... Market Street.
What a great pub name: The Market Porter.

... Four men are sat by the front door, getting a couple of pints before heading home to Southampton after a 12 hour shift on the nearby Crossrail construction. “A few of us try and come here once a week. This place is great for people like us, it’s our evening,” says Steve Webb, one of the workers.
Early houses came about due to a quirk in Britain’s alcohol licensing laws. Historically, all pubs would serve from first light, before this was stopped in the first world war because it was seen to hamper the war effort. But an exception was made for market pubs.
“Market business was often conducted in the pub. You’d go have a look at someone’s cattle or sheep, and then go into the pub and strike the deal with a drink,” says Martyn Cornell, a historian specialising in beer. “It was almost a commercial necessity to keep these places open, so market business could be carried out.”
