The biggest headache is mobile phones. For spycatchers, these are ideal bugging and tracking devices, which the target kindly keeps powered up. But that makes them a menace for spies (and for terrorists, who often operate under the same constraints). Removing the battery and putting the bits in a fridge or other metal container disables any bug, but instantly arouses suspicion. If two people being followed both take this unusual precaution near the same location at the same time, even the most dull-witted watcher may infer that a clandestine meeting is afoot.
