Does anyone know in which comic these things happen?

1. Robin (Jason Todd) asks for a glass of milk at a hardcore bar with prostitutes and drug dealers.

2. Nazi saboteurs come to Gotham City (Probably in the 1940s).

I don't think the first one ever happened. Second one sounds like Detective Comics#65.

Without going through my trade paperback collection I could not tell you.. but I think the Jason todd asking for milk may have happened in either the batman the cult book or the batman Alan Davis collection book and as for the nazi saboteurs that happens is collected in either batman chronicles vol 3 or 4 not sure which..
When I get home I will confirm both answers more correctly.

Barr/Davis run, this article shows the scene from Detective 570:

Detective comics #55 has men that are eluded to be Nazi saboteurs agents working undercover printing and distributing propaganda or something like that.. it all ends with Batman and Robin fighting them on an inflatable Air ship dirigible thing.. if that helps.

The second one sounds vaguely like Archie Goodwin's "Heroes", from the first volume of Batman: Black and White.

Could it be from the Batman and Captain America crossover?
