For context I'm graduating a 4-year course after 5 years (after taking a year out for medical reasons) and at my uni we have 'Personal Academic Tutors' which is sort of a form tutor you're given who takes 4/5 students in the year under their wing to help in any and all aspects of university life. My PAT has been amazing and helped in sorts of situations that no one else would and honestly, I would have been a complete and utter mess without her. I also know from talking with my mates on the course that theirs were all rubbish in comparison. She does not have any influence on my grades and is not one of my lecturers.
Is it normal to gift her something to show my appreciation? I'm wary of anything food/drink related because I have no idea what her preferences are
