Play for tips in the subway. That might work.
I'm in SV.
A quick and easy fix for that:
Go into edit town, and drop a very small lot somewhere. It doesn't matter where, so long as it's on level ground and close to your Sim's home for convenience. 10x10 will be plenty big enough, and there will be no shortage of room to drop one of those. Once it's been made, change the lot to a community lot and go into build mode. Locate the subway object and place it on the lot. Done!
I don't remember where it is, exactly, but I'm relatively certain it's under "Community Objects" in the build menu. However, if it's not there, it should be in the buydebug menu under "Misc" (the 3 dots in a triangle pattern).
You only need one since you're only using it to play for tips, and not traveling.
