It's almost impossible for most players, most people even, to imagine life as anything except modern 20/21 st century life. Life was very different before 1900(or really 1950), but most people have no idea what it was like at all. And life in say 1300 of D&D times, is even more so beyond that.
Take the Inn Example. To a modern person, once they ''rough it" for a week in the wild they do just love ''getting back to normal" of civilization: running clean water, made food and drink, a soft bed, fun and games. Though this is from a modern person who has all that in normal life. The average adventurer type most likely grew up on a farm...in 1300-1500. So no running water, no electricity, no phone, no lights, no motorcars. They eat and drank things that were not exactly ''supermarket clean'. Most everything was room temperature (no refrigeration). They had to hunt and trap and kill and prepare all most all their own food. They did not bathe much...maybe once a month. They made a lot of their own stuff. Made things were crude too, but that was the best they could do without machines and modern materals.
So the typical rough adventurer would not much stay at an Inn.....that is a place for ''soft" people. To use the modern equivalent: it's like having a servant feed you with a utensil and you'd stand still as they would wash, clean and dress you. Few modern people would like that...
