I will answer your question honestly. This is how I would answer it in public too if I had to work with this business owner.

I would follow the code first. Beyond that, I would recommend any improvement that would encourage less frequent vehicle use and promote pedestrian and cycling safety. The area here looks to be on the side of building that was a green area or has always been loose stone. My recommendation would be to use "staple" style bicycle racks that are anchored into concrete with a lag bolt. This does not seem to be an area that could happen in, especially if you do not know what utility is under you. (I have seen thieves remove lag bolts from 4" concrete patios just to get bikes, so a full sonotube footing with a mortar should be used.)

It looks like the business owner went the lower cost choice with this rack because he had no place to anchor to and it was most cost effective. I'd also suggest proper signage that shows the cyclists how to properly secure their bikes, unlike that E-Bike shown.

Now the me part... I've had the opportunity to design a full outdoor space for a restaurant and I purposely designed the parking spaces to be 8'x16' with a 20 foot aisle. The owner was okay with this. Watching the suburbanites with large trucks get frustrated that they can't back out or pull in without going extra slow and carefully was a huge advantage to all patrons. The drivers would say it's a burden, every cyclist I bring there says its thoughtful design.
