Before engaging, it is essential to evaluate the non-fulfillment risk of the main goal, because local events are not always a decisive factor. If it fails, the real question is: what protects us from the failure of our primary mission? A beer festival nearby won't stop a bathroom renovation if the mandate is to work. The stop condition is not a higher price but the impossibility of completing the main task, such as not finding accommodation at all for essential training. The question is not about participating or avoiding but whether our real goal is compromised.
