Staff don't use it correctly – Supercuts Hair Salon Check-in Review

I used the app to check in for 5:15pm, showed up at 5:10pm and was told that the stylist just began coloring someone's hair and would then still have to wash and cut it. I asked how long it would be and was told closer to 6pm. I got a babysitter to go to my time slot and think it's ridiculous the stylist would take such an obviously long appointment 10 minutes before mine. The check-in process requires my phone number and the least they could've done was call to let me know about the delay.
