Case 4 - Final Location Clue
Scroll down for more clues and the answer.
Look at the top right of the desk to establish todays date, then take a look at other items on the desk.
Any venues visited in the 2 days before the 26th of March can be ruled out, this should leave only one possible venue.
Tickets to the theatrical grill on the 25th and the receipt from Tillies Chicken on the 25th rule out these venues. Leaving just one venue left that the booze could be hidden - The Log Cabin. Use the number next to the Log Cabin 872 to open the final chest and get your hands on the booze.
