<human>: The other day my fiancees gram called me "completely unreliable" because I didn't go to the liquor store to buy her a bottle of bourbon. I was unable to do this because after working from 10:30pm Thursday (Thanksgiving) until 8:00am Friday, I was asked to come back in and work a second shift since someone didn't show up. So I got about 2 hours of sleep and went back in until closing. I work Gamestop, it was black Friday, we were packed. However since I never got a chance to pick up her alcohol, I am completely unreliable, even after she found out I worked two shifts.... Reddit, what ridiculous things have you been called by someone only concerned about their own petty wants?

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: My fiancees grandmother called me unreliable because I didn't pick her up a bottle of bourbon like she asked because I worked a double shift.
