the serial port cant read a switch like that. the serial port expects 8 bits of data, with a start bit and stop bit, (total of 10 bits). also the baud rate needs to be set to a particular rate. that cant be done with just a switch.

You use the MScomm tool (project>>components>>controls tab>>Microsoft comm control 6.0) to 'listen' to the serial port. After that it's a simple matter of counting the number of times a signal was received from the port. Maybe divide by 2 to account for coming and going of customers.
