You would be better to target vending machine manufacturers who supply to major soft drink and confectionery products that are placed in very visible areas such as rail and bus interchanges as well as airports and stadiums.

Other types of vending machines include power recharge and even water (cold and frozen) vending machines.  The number of these types of vending machines is increasing all the time, schools, colleges and universities have them also.

Ride sharing companies such as Uber or their competitors that are springing up should also be approached - the advantage is a cashless ride which gives the driver greater safety as they are less likely to be robbed.
