The retirement community my elderly uncle lived in worked with a local hospital that would schedule all the appointments for the same day, around the same time. They had almost every specialty in the same building so the residents could see the various doctors they needed. But if you had your own doctor at a separate place, you could schedule it ahead of time and they would drive you there. However this was a high-end community that cost a lot, so I’m sure if cheaper places would offer the same options.

This reminds me! At work we often send emails to customers through our ticket system so they are recorded. A new guy got a pop-up asking if he wanted to send the email. He looks at me and says “What do I do?” I say “Well you have 2 options: Yes to send the email or Cancel.” He clicks Cancel and is then confused the email never sent. He quit a few days later which honestly was better for all of us.
