Coworker wants a betta in a bowl

I was talking to my coworker about how she was interested in getting a betta fish since I’ve been really into fish keeping and another one is something of an expert with a 55 gallon tank

I gave her some advice and answered questions. And…She told me that she wants to get it in a bowl.

I was telling her she needs to get a tank with a heater and filter but she told me it doesn’t look as pretty :U I hope I can steer her away from that but I doubt she’ll listen.
