I bought a platform ticket yesterday. The ticket man was rather
surprised that this was what I wanted. (I'd arranged to meet a friend
mid-commute to hand him some books.)

I thought it would be easiest to ask a Real Human™ for one but wonder:

Could I have bought it from the touch screen machine?
(I wasn't going to faff about to find that the machine didn't do them)

Would I have upset my Oyster if I'd tried to use it to open the barriers?
It's a Bus Pass with PrePay.
(I didn't try because I didn't want the Seek Assistance business.)

Does anyone here know the answers?
