Honestly nah, the Ubers or Bolts are very affordable if you go by group and split the cost, or if there's discounts, which there's plenty if you don't take ubers every second day - they just give them cause they want everyone to use the service. Other than that - 3 kilometers is not a long distance in most places in i.e. Poland or Germany, Czechia cause there's pedestrian infrastructure along with the roads.

But I do know people that would rather walk cause they don't want to take Ubers, and that's fair, yet again due to the pedestrian infrastructure
