Why is tipping becoming so aggressive at restaurants lately?

So, a couple of days ago, I went to a restaurant in Andheri with my girl. It wasn't a fancy place, just an average restaurant. The food was good, but the service was nothing special—I had to call the waiter 3-4 times to get his attention. When the bill arrived, it was around ₹1450, which already included ₹200-250 in service charges. My girl was paying online, and when the waiter came with the scanner, he straight-up asked, *"*Chalo apko jitna tip dena hai de do, 100-150 jo marzi*"*. He even repeated it a couple of times. We just paid the bill amount and left awkwardly, but while leaving, I noticed he was giving us an angry look. Bhai tf? The bill already has service charges, and you're still directly asking for ₹150 as a tip? A few months ago, I went to a fancy restaurant where the bill was around ₹4000, and it included ₹900 as service charges. Even there, the waiter asked if I wanted to tip. I ignored it, but he asked again. I had to tell him, *"The bill already has ₹900 in service charges,"* before he finally backed off. I don’t understand why this aggressive tipping culture from the US is creeping into India. Tipping should not be mandatory. If you want more money, ask your boss to increase your salary—don’t pressure customers. Always check if service charges are included before tipping. If you genuinely want to tip, that’s fine, but don’t feel obligated. Share your experience too, if you faced such situations!
