Tell Sam's club to go f--- themselves by calling out this Saturday since you'll be the only one in all of tech (since everyone else calls out and gets away with it anyway) plus you'll be doing phones for 16hrs straight and fixing f---ed up orders every 3rd order or diffusing and angry member with free gift cards or sh--dogs from the cafe to calm them once they realize their 8 activations will take 2hrs.
Let them get f---ed over and wish they replaced you with smartcircle long ago then use the day to go apply at a place that actually cares about their employees
