6 july 1968 & new bus policy re exact fare

#OTD 6 July 1968 Bus riders were adjusting to a recent policy change that eliminated bus drivers' dispensation of cash between the hours of 8pm and 4am. Prior to the new policy, which began on 11 June, bus drivers provided change to passengers who did not have exact fare and also sold tokens to passengers. However, after an attempted robbery led to the death of a bus driver on 17 May, bus drivers, supported by transit union Local 689, refused to operate buses if they had to carry money. They demanded that DC Transit and the Washington Metropolitan Area Transit Commission adopt the use of scrip.

With the new policy, bus riders had to have the exact fares or tokens. If they did not have the exact fare, instead of change they would receive "a redeemable scrip coupon," which showed how much change was owed. The passenger could redeemed the coupons, get their change, at select locations. 

Your comments are welcome below. Did you, family members and neighbors ride the bus in 1968? Do you remember the change in policy? What did you think of it? Were you a bus driver? Did you work in another capacity for DC Transit? Were you in the union? What buses did you mostly use? You may comment privately here.
