Covert cutting
In lieu of following the procedure mentioned above, some will "cut in line" by joining up with family members or friends already standing in line. This action is usually more acceptable, but can still be considered "cutting." Many times, this action is purely out of convenience, when one member of the group "saves a place" for the other members, especially when the wait is lengthy. However, this is not always the case. It is more acceptable when the two people are simply together to conduct one transaction, however if both people plan to conduct one transaction each, it is particularly disrespectful (especially in queues with slow cycle times due to high individual transaction times).
Other forms of cutting
Some consider leaving a line and returning to the same point later a form of cutting. An example might be a person waiting in line for an amusement park ride who realizes that he or she would like to leave behind an item (such as a coat or beverage) with someone else. Should the person leave the line, relieve himself of such an item, and return to his place, some might consider the act cutting (even if it were known that the person was in the line previously).
National attitudes
In former Communist countries, where waiting in long queues was a near-daily occurrence for some, especially at times of rationing, the act of waiting in line and the code of conduct associated with it is much more institutionalized and regimented to this day (See Consumer supply in the Soviet Union in the 1980s). In Russia, for example, the art of queuing is finely-honed: it is acceptable for a person to leave the queue to use the bathroom (or similar brief diversion) and then return to their original place without having to ask permission. It is also common for a person to be allowed to jump to the front of the queue in special cases, like the need to purchase a ticket for an imminently departing train. This can also be seen in Cuba, including notably at the Coppelia ice cream stores, and in Spain where an arriving patron asks "¿Quién es el último?" (Who is last?) and is then behind that person in the queue, which is not always a physical line.
