how to deal with unprofessional preceptors during clinical shifts

it just sucks that i'll be stuck with this preceptor for the next few weeks since i'll be graduating soon from the medic program. i picked them because they were coaching me during the previous couple shifts that i've had with them and seemed great. i had no previous problems with them.

we get called to a fall call and find this lady sitting hunched over her chair, with the witness that called 911 telling us that he saw her fall a couple steps down his store. before i even talk to her and begin my assessment, i notice the several open bottles of jack daniels and don julios laying down and sitting next to her. i walked up to her, and she reeked of both alcohol and urine. no head/neck pain, no LOC, just a slight soreness that she feels on her right arm with no deformities/abnormalities etc. she's A&Ox4, but has some light slurring in her speech. she said she wants to go to the nearest hospital, and i was like okay! me and my preceptor help her off the chair and guide her up towards the back of the truck.

her v/s look great, and so my preceptor's partner ended up driving. then, this conversation ensues while our truck is moving to the hospital:

pt: "i really have to pee do you have anything that i can pee in"
preceptor: "no we don't have anything for that you better hold that sh*t in" (yet there's empty urinal bottles that are stored in some of the upper compartments that i didn't see until after the call)
pt: "why are you so aggressive?"
preceptor: "im sorry that you think i come off that way"
me: (thinking of a way to steer the conversation somewhere else) "hey [insert pt's name], do you live around here in this area?"

then, we finally pull into the hospital. as me and my preceptor stood up, we saw the streams on the floor of the truck and the damp spot she left on the seat. my preceptor immediately goes, "did you just piss in my f*cking ambulance?" and the pt kept apologizing. preceptor replied, "too late for that let's just go."

yeah, idk how to feel about my preceptor anymore after that call. i'm debating on whether or not i should tell my clinical coordinator about my preceptor's actions after im done being precepted by them. i fully understand that working in this job will make you extremely burnt out and want to wreak havoc on certain patients, but that gut feeling of mine is telling me otherwise about how my preceptor acted towards that pt. maybe it's because i haven't worked for that long in 911 which influenced my gut feeling about that.

TLDR because at this point im rambling: Capstone preceptor cursed at a pt who was intoxicated and later pissed in the ambulance. looking to see if other students experienced a similar thing.
