Robi. the problem with Walgreens is that they are cutting hours even in the management ransk that it is affecting morale. I have been a MGT for almost two years and I have yet to complete all of my PPLs. This is preventing me from applying and becoming an EXA.
I am an overnight (graveyard MGT) and when the night shift does not do their End of Day, that causes the main computer to freeze up all the registers. It always happens when the pharmacy and the front check outs are busy too!
In your case, you have to pull the drawer LOOK inside the till to see if the check got stuck in the back of the till. There is no way to find the route number because there is no recording system when you run a customer's check through the check printer. That stinks. It is stupid but that is the way it goes.
When they sprang me loose on the graveyard shift, I didn't know how to do voids and refunds so I was stuck there scratching my head. I had to call three other Walgreens for help. Bad training.
