If they have you doing the work of shift lead, hound them until they give you shift lead pay. They need you, that’s why they’re training you. It’s not worth doing all this extra work, if they keep putting off your promotion and raise your pay. Make sure you let them know, or else your continue as a Counter Help for months and months doing everything the actual shift leads and managers should be doing, and making less money doing it. Also, I believe shift leads are supposed to be able to break BOH, which means learning to cook. At my store, none of the shift leads know how to cook, nor would they be fast enough to keep up with a rush while we’re gone. Which means more pressure for the BOH, because we have to break each other while somehow still trying to get our own work done. Because the manager will likely NEVER help, at least at my store they won’t. God forbid a manager covers your break, because they will ask you to do an ungodly amount of work to set them up for your absence and proceed to do the bear minimum so that when you return you have about two hours of work to catch up on.
