Students generally do not feel obligated to give gifts to professors after receiving letters of recommendation or assistance. The consensus is that the best way to show appreciation is through academic success, such as earning a PhD and becoming a competent scientist, rather than through material gifts. While some students suggest informal tokens of gratitude, like cards or small presents for close mentors, many believe that simply thanking professors and sharing acceptance news is sufficient. Gifts could even be viewed as inappropriate or akin to bribery. Overall, the focus remains on academic performance and maintaining a respectful student-professor relationship rather than on gift-giving.
