Movie cinema prices for the same movie

For two days in a row, I have tried to watch the movie "Final Destination 3" in the cinemas. The first day I was called out due to work. Yesterday (day 2) I managed to watch the complete movie.

Since there is construction going on at N1 City, the late night movies are not shown at the Nu Metro cinema at N1 City. Yesterday I did not make it in time anymore for the 19:15 show at N1 City, so I went to the Nu Metro cinema at Canal Walk, since the same movie only starts there at 20:00.

The same movie for more or less the same time was a bit cheaper at N1 City than compared to Canal Walk. The N1 City cinema is also a lot smaller with fever visitors so the prices cannot be pushed up too high.
