It depends on (sub)culture, but mainly yes.

Bars were often cheap too, so going to the bar multiple times per week was not expensive. The reason these bars were cheap:

• Outside of touristic areas ground is cheap.
• If the local government allows it, the bar can on the owners property.
• The owner and customers were often friends, so friend pricing would be standard.
• Health and safety regulations used to be less strict. Allowing for lower prices.
• The bar was open whenever the owner wanted, instead of on a fixed schedule, making it more easy to combine with a second job.
• Bars rarely had a menu, they just sold whatever they had in stock. Today customers would be upset if an item on the menu was not in stock.

Also,

• Parks used to be less safe and less well maintained, so buying drinks in the supermarket and consuming them in the park wasn’t really an option.
• The internet wasn’t a thing, so people who wanted to spend the evening gaming had to do so in the bar.
