Straus Calls

Straus Calls is an unmarked quest in Fallout: New Vegas.

Walkthrough
When heavily wounded or irradiated, it is always advisable to visit a doctor. If you're short on caps, find doctor Ada Straus at Novac. She has cheaper rates than the average doctor: 50 caps to remove addiction, flush radiation, or recuperate from injury. If you go through all services in one conversation, the price can come down to 40 caps.

She also sells numerous items: average medical supplies, addictive chems (most doctors don't carry these), laser pistols, and energy cells. She also carries a few components for mass purified water, such as and dirty water water and glass pitchers. This may prove useful, as Novac doesn't have a clean water source.
