The longer I work at my current place of employment, the ballsier I get. If someone asks a stupid question, I give them a stupid answer. When frustrated with the answer I proceed to tell them I cannot do my job properly if they cannot propose a question properly. Most times people just play it off as me being funny but really I hate you people Retail is killing my good natured spirit.

Because of that it seems to affect me in other places when shopping or the like. I will be more likely to voice my discomfort of a situation than I used to. Such as your line queuing incident.
