If you term every Traveler as Bhakt then that speaks volumes about what kind of vendetta you actually have then anything else.
I'm a somewhat regular traveler of Vande Bharat Express, you DO realise they're cleaned right away right ? Regular Announcements are made publicly many times ? And IF you had used the Washroom Facilities yourself you would've realised the Toilet there needs relatively more frequent flushing than regular ones due to design.
They're not overflowing, people aren't exactly familiar with operation of that. High Speed makes things worse as most of...
more... movements of Coach is around that area hence people feel it as overflow.
Can't believe I'm talking about Toilet in Public Forum. Maybe instead of whining about something travel in it first ? That's coming from someone ACTUALLY paying for those extra money that you so eloquently put there.
