Service stations on my route in the UK went from having 2-3 medium-speed chargers total in 2019 to having 2 rows of 20 high-speed chargers, and another parking doubling that is under construction. The same happened all over Western Europe - grew from a few singular chargers at supermarkets and hotels to many large charging hubs along highways.
Reliability and ease of payment also got better, partly because regulations started requiring it, but also because the stations don't sit idle any more, and it started to matter for revenue.
Also in EU there's enough charger coverage now that there's competition. I don't have to sit in line to the only charger in town, I can drive few miles to the next station.
Parking garages are also getting EV chargers. My office garage just added a couple dozen, and I don't think it would be hard for them to convert more once the demand shows up.
And I've seen them starting to go in at the little rest stops on the Autobahn that up to now only had unattended toilets; they're being added to the big, nice rest stops with gas stations, too, of course.

Depending on EV adoption and how much charging people want/need, you can start with a couple spots that are active charging only, and see what that looks like. If the chargers are always full, consider adding more and/or having several spots for each charger and standards and practices to move your car and the charging plug when yours is full, etc. If the chargers are underused, consider making the spot open when the lot is full, etc.
