Comparing a bill for a night on the town to a bill for what most would consider a necessity is asinine. The industry is well aware people rely on cars for Jobs, Doctors appointments, Kids, you name it. They are also aware the bill for said car may be prohibitively expensive, therefore they tend to work with people on payment dates (at least most shops will). Furthermore this type of scenario is how alot of smaller shops tend to retain business, as they are more willing to go out on a limb for the customer.
