i've been to that store a couple times this year and no sign of her there , but i only go there on saturdays like maybe once a month of i was in the area so unable to go there at other times and such
but its one of those big chain thrift stores and maybe she moved on to something else , i'd imagine its fairly common for staff at them to not stay long term and move on to something else sooner rather than later as its not a high paying position
