On tipping:
Try giving a tip to people not regularly receiving one e.g the “Dönnerperson”. Since tips are non obligatory these people usually are extremely happy about it.
In tested the hypothesis that Dönner is larger when visiting a place where I tipped before and measured 10%-15% increase in weight ( 5 places, 3 Döner each, weight difference between fist and third).
