Putting the phone down without saying goodbye.

Making a date on the phone without arranging a location or ETA. 'do you want to go for a drink tomorrow?' 'uhh, yeah I'd love that'. 'take it easy'. End of conversation. WHERE Are You meeting her you stupid ****??

Person A has a confession. Person A attempts to confess to person B, but Person B unrealistically interrupts to the extent to which Person À doesn't get secret out. Person B then says 'what were you going to say a minute ago? Person A then looks sheepish and says' oh, it was nothing'. This secret comes out in the film later on, Person B is then furious with Person A for not confessing earlier. Always happens in soap operas in particular.

Arabs in movies will usually steal stuff.

When a character is getting chased, or trying to escape something, keys never go in locks easily.

Coughs or sneezes always lead to serious illness/death later on.
