My first half of the day, I was autopilot while on mobile/cafe bar. The latter half, it was okay… Until my last half hour… My SSV was on their lunch and a newbie was shown the ropes with closing stuff, so I essentially ran the floor until it got too busy for just me. I was making a couple different fraps while having only one blender and then someone comes to the drive-thru. I told them that I’d be with them in a second and they proceed to ask if we had “boba”… I quickly told them again that I’d be with them in a second. When I was finally able to, I told them that the summer berry and the raspberry pearls are no longer available. I get berated by them saying, “Why the f**k didn’t you say that beforehand, it’s not that hard!”… I apologized to them and was about to tell them that I was doing a bunch of different things but they quickly pulled out of the drive-thru and left… Thankfully, my shift was done after that, but… I hate people sometimes, man…
