How long does it take to get a multiple-entry tourist visa for Thailand from the Frankfurt consulate?

The original post discusses a couple's concern over not receiving feedback on their multiple-entry tourist visa application submitted to the Thai consulate in Frankfurt, one month prior to their flight to Bangkok. Commenters suggest checking the spam folder, the e-visa status, and mention that the Frankfurt consulate often has long processing times, with some hinting at contacting them via social media for updates.
