I have applied in Munich, Germany to have a tourist visa to visit UK. Usually, from experience, how long does it take to have the decision made? I have tracked my visa through TLS. Thanks in advance!
According to the statistics published by the UKVI service (which you can find here) 99% of tourist visas handled through Munich in August 2018 were decided in 15 days, with 100% being decided within 30 days.
Note that these are actual figures for actual visa applications. Some visas take longer than others so this is not a guarantee that your application will necessarily be decided as quickly.
