Actually, IMO, “let me google that for you” would be more helpful than just telling the questioner to google it, since the respondent actually did do the work and googled it for him/her.
I do try not to be snarky in my responses because this is a stressful time for these students. But as mentioned earlier, some of these questions have been asked time and time again. It never fails to amaze me that some of these posters think that they are the very first person who thought of this particular question.
