My mom and I stopped by to pick up drinks to go....we went inside since the drive thru line looked long. We're pretty understanding since we knew the drive thru was busy and there was only -one- barista making drinks. Even though there was one employee strictly taking drive thru orders and two other employees off to the side just socializing. I'm not sure how this particular Starbucks manages work flow but it appeared the one lone barista could have used some assistance. I noticed the average wait time was beginning to flash red for the drive thru as well. Eventually my drink was made but then the girl completely forgot my mom's drink. Which became obvious when the couple who ordered quite sometime after us got both their drinks. We saw a drink sitting in the blender which we realized was my mom's. The girl at one point appeared to recall the drink, blended it a few more times and then forgot it again making other drinks. When we notified another employee about the situation she asked if we would still want to taste it to see if it was ok....we politely asked for it to be remade. When we finally got the drink...there was no service recovery or anything. I work in service industry as well and the very least I was looking for was a "sorry about the wait." Literally nothing. A quick stop turned into a 15-20 min wait. I hate writing negative reviews but this was pretty disappointing since my mom was getting upset and we ended up being late to an appointment. Drinks were on average and as expected.
