EVANSVILLE, Ind. (WHAS11) -- A new policy is in place at the University of Southern Indiana in Evansville and it's leaving some students with a bad taste in their mouth.
The cups in the school's dining halls have a tiny sticker on the bottom, keeping track of the time.
Students can only get one drink refill in 90 minutes then they're cut off.
School officials say the change was necessary because people were taking advantage of the system but students say caffeine is an essential part of college.
If the cup doesn't have a sensor, soda will not be dispensed.
USI says the next step will be monitoring the new system and getting feedback from students.
