at work

there is this manager who is dating a driver but clearly flirting very hard with a DIFFERENT driver who also is in a relationship and it is literally insane. i feel like i'm watching someone get cucked at work. like she will have him buy her food and make sure he stays late and talk to him real close. she like BEGGED him to take someone's closing shift tonight so they could hang out and drew a HEART by his NAME!!!! he erased it a few minutes later but i am so uncomfortable with this situation like it is ABSURD
