I don’t think OP meant condescending to the person’s teammates so much as condescending to the reader. The person over-explains each option and I can see how it would read as ‘wow, you are really dumb and obviously need some handholding to figure out simple decision-making!’ That likely wasn’t the intent, I understand, but I get why people might take it that way.
No one thinks much about cybersecurity while traveling. However, email security company Tessian warns the out of office message actually plays right into the hands of threat actors and cybercriminals. It’s a social engineering attack vector that no one thinks about. The out of office message is ubiquitous and handy. But if it includes any personal information at all — such as attending a funeral or going out of the country — attackers have all the information they need to impersonate the person who is out of the office, without the attacker having to do any real work.

Thanks for reaching out. Unfortunately, I’m out of the office from [day/month] to [day/month] with limited/ no access to email. If your question can wait, I’ll be responding to any emails I miss when I return. If not, contact [Name] at [email] or [phone] and he/she will take care of your request.
A. No. All of the restaurants, including Starbucks and other eateries in Thompson Student Union, will be closed during winter break. They will reopen the second week of January.
