Cause for immediate termination

What would you consider grounds for immediate termination of a brusher/bather/pt groomer? I will go into the long story later, but I am curious what you would fire over with no warnings or write-ups.

for example ....

injuring a dog and not fessing up
stealing
leaving a dog unsupervised or unattended as is appropriate for the situation the dog is in
lying
cussing to, or in the presence of, clients
causing a dog to escape due to negligence

i'm sure there are more!

*start date 1/16 2 days a week hourly) plus commission grooming on other days Plus she works for the daycare I sublease from
*second day, called in sick-dog ate advil at ER all night
*next 2 days worked came in late
*text message not coming in because working at other job.
*1.5 hr late next work day(missed bus)
*leaves early frequently(friend is here, meeting someone, has plans..)
*5 more work days late for 3
*did not show up for grooms. " I did not know" but she did come in and groom them.
*Was told she could not leave til grooms had been picked up but did anyway.
*Called in Mom had heart attack and may have to leave town. Gave day off
*Groom 2 days later. did not show up/call/text. "forgot w/all that is going on..."
*groom following day told to stay because I needed to talk to her. She was there when I got there. I went to the office to print out a formal warning and talked to the girls up front a while(15 min) I went back and she had left a dog under a dryer (medium heat). Did not tell anyone she was leaving, but had sent me a text msg that she had to take care of something. My phone was in the grooming room with her and I was in the building. So I text her to come in before her shift with the daycare so we could talk. She asked "you don't need a bather" to which I replied "no".
Next day when she was to come in before her shift to talk to me. No call/text, but did manage to call the daycare manager and let them know she was running late.
Owner of the daycare wants me to talk to her, but at this point I am wondering why? Yesterday I was prepared to let her off with a stern warning even after she left the dog under a hot dryer unattended, but when she blew me off for lunch with her friend and did not call/text me, I was fit to be tied. She obviously does not want this job.
Uggg. I have not formally warned her, so I am feeling a tad bit bad, like I should at least talk to her. The owner of the daycare is coming in at 3 tomorrow so we can all talk. I just afraid I won't be very nice at this point.

Pack your stuff and get out, that's all I would say. This person does not warrant any second chance or anymore of your time. I can't believe you put up with as much as you have. Sounds like a major drama queen and even if you talk to her chances are she is just going to cause you more aggravation in the future. Tell her bye bye

Dog left under hot dryer. That would have done it for me.

Glad I don't have employees, did you get rid of her?

Yup. She still works in the daycare. She said she had too much on her plate...w/e
