<human>: Can you provide a brief rundown of the text in within 3 sentences?

Actually happened on Thursday- I'm working as a pharmacy technician for the summer, and for the most part I've received glowing reviews about my customer service, as well as being good in the assembly process. For those who don't know, many larger pharmacies have a station system where one person fills the prescriptions, one takes new ones, and one fills the less urgent prescriptions while manning the cash. The pharmacist will handle consultations and inspects every prescription, whoever has a moment then goes and puts the ready bags onto a shelf. So on this day I was on the hybrid station and was scanning out this guy's prescription. We have plenty of regulars and this one guy comes in for his AIDS medication frequently. However it's my second week working here- I have no idea what his story is yet. So I give him his prescription and he brought other items from the frontstore so I scanned them and was gonna put them in a bag until I remembered a coworker (quite hilariously) had fallen on the bag rack and effectively tore every single one off by the handles, rendering them useless. So me being the smartass I am, I tell this AIDS patient "here, let me dig into Brokebag Mountain to find one for you." Suffice it to say, he went ballistic, demanded to speak to my boss (the pharmacist who also happens to own the store) and moved Heaven and Earth in attempts to get me fired. My boss later tore me a new one but I haven't been fired as he realized it wasn't intentionally malicious.
<bot>: made a gay joke unknowingly to an HIV-positive man. He was a wife apparently too. /cringe.
