<human>: Basically at my job site we have 'push for service buttons' which conveniently are located next to the push for ticket button (parking garage) at our entrances. 

100s of times a day people are pushing the wrong button and either don't say anything when we answer the intercom or immediately and annoyingly yell 'SORRY!!'

Besides being annoying, it also can plug up the intercom line with too much traffic when we leave the office and are patching the calls through to a cellphone. 

Yes the ticket dispensing button is lit up, says push for ticket..the other button is clearly labeled push for service...I just want to find a cover for the button..I imagine that if a person had to lift up a plastic cover they may reconsider before accidentally pushing the 'wrong button.'

Can you succinctly summarize the text in 1-3 sentences?
<bot>: poor design, ticket dispenser button next to push for service, accidentally pushed over and over again, looking for a button cover, google fails me.
