Vendors can't roam in coach with food bcs it's difficult for them to get in and out of the coach, due to rush. No trains available at night for vendors to reach their home at night if they travel till shimoga from talguppa then they shld wait till morning at shimoga for talguppa train and if they are from shimoga then it'll be late night so people won't prefer food at that time and not ready to lose their sleep it makes vendors to throw their food without buyers, if they sell at shimoga station means no time to buy bcs train halts for jus 10-15mins more over no one is ready to buy bcs getting in to coach itself is a big problem, so better to have ur stomachs filled before getting into train. Coffee tea are available at arasikere u can have there.
