If she forgets to give money after helping a colleague buy something, here are some ways to deal with it:
1.Tactful reminder: You can choose an appropriate moment to tactfully remind a colleague that she hasn't paid yet. You can say, "Did you forget to pay me for the things I bought for you last time?" Remind her in a relaxed tone to avoid making her feel embarrassed or uncomfortable.
2.Direct communication: If you don't feel like a tactful reminder is working, or if you have a close relationship with a colleague, you can communicate directly and honestly with her. For example: "I haven't paid for your groceries yet, have you forgotten?" Explain the situation directly, but pay attention to the tone and manner of the situation, and don't make the other person feel unpleasant.
3.Wait for a while: Sometimes a colleague may really forget, you can wait for a while to see if she will remember on her own and offer to give money. Maybe she needs some time to take care of something else.
4.Don't dwell on it: If the cost isn't too big and you don't think it will have much impact on your relationship, you can also choose not to dwell too much on it and treat it as a small thing. After all, a good co-worker relationship is more important than that money.
5.Seek a common solution: If a colleague does have a hard time making timely payments, you can work with her to find other solutions, such as paying in installments or compensating you in other ways.
6.Avoid embarrassment: When dealing with this issue, try to avoid embarrassing or embarrassing your colleagues. You can choose to communicate privately with just the two of you, or remind you through chat software, etc.
7.Consider future collaborations: If colleagues often forget to pay, you may want to consider communicating the cost more explicitly in future collaborations to avoid similar situations from happening again.
