Take a look at ADA requirements regarding ramps: https://www.adawheelchairramps.com/wheelchair-ramps/ada-guidelines.aspx https://www.adawheelchairramps.com/wheelchair-ramps/ada-guid... You need at least 30 feet of ramp for a 2 and a half foot incline. I don't know about the environment this coffee shop is set in, but these standards would make it impossible for non-corporate shops to exist in many cities around the world. Most cities don't have 30 feet of space outside open and free for building ramps that (being generous) 0.1% of every store's potential customers will use. You can compact that 30 feet with a couple bends, but then you vastly increase width of the sidewalk space required. Assuming this building doesn't have a mass expanse of free space extending around its premises, it probably required restructuring of the building itself, which takes quite a bit of time and money, as well as lost business while this single person waits for their coffee or $60,000.
