Rude Staff at the ticket office

I came not for once but several times and Stan in a queue to load the bus card ,the service is very poor staff working at the till counters doesn’t even greet and they are always angry shouting at commuters .the behaviour is not acceptable this needs to be addressed as these buses are for the municipality and not theirs .customer service requires one to be friendly and welcoming at all times.i will report this to the Head of the Municipality as well .
