Did I Get Scammed by an Elderly Woman in Delhi Metro?

Yesterday, I was traveling through Delhi Metro when a woman who looked to be in her 50s approached me at Rajiv Chowk. She seemed nervous and asked for help getting to Inderlok. I helped her figure out the route and later showed her the correct line at Kashmere Gate. After that, she told me she didn't have money for an auto-rickshaw and asked if I could help. I gave her ₹40 because it wasn't a large amount and she seemed genuinely worried. A few minutes later, I noticed her talking comfortably with another person and then walking into a shop with him. That immediately made me wonder if I had just fallen for a scam. What made me even more suspicious is that a few months ago I had a similar experience. A guy approached me and claimed his phone was broken, so he couldn't contact anyone, and asked if I could lend him some money. At the time, I helped him too. I'm not bothered about the money itself, but it's strange that I've now run into two different people with emergency stories asking for cash. Maybe they were genuinely in need, or maybe these are common scams that rely on people's kindness. Has anyone else in Delhi Metro experienced something similar? Is this a known scam, or am I just being overly suspicious?
