Is the petrol station area (J1, J2, J3, J4) in some way connected with the café and restaurant of the community centre (G1,G2)?
There is no link between petrol station J and community centre G. J is meant to replace the existing petrol station near Dunklergasse. The same applies to fast food drive-through H. There is no link between Burger King H and community centre G. H is meant to replace the existing Burger King near Dunklergasse.
