<div dir="ltr"><div>>> If a Jew works as a cashier for a supermarket and another Jew asks them to ring up some bacon, saying it's for<br>breakfast, what's the halocho? <<</div>
<div> </div>
<div>According to Sefer Binah VaDaas, the guidelines for this sort of thing are:</div>
<div> </div>
<div>a) If the fellow can get the Issur on his own - comparable convenience and comparable price - there is no LIfnei Iver and only potential Mesayei'a MiDerabanan (or perhaps someting akin to Chizuk Y'dei Ovrei Aveirah) according to some Rishonim, and a Baal Nefesh Yachmir (Rema YD 151:1). There may be an additional Kulla in a case where there is no Siyu'a at the time of the Aveira itself. (See Shu"t Binyan Tzion 15, Ksav Sofer YD 83).</div>
<div> </div>
<div>This is all if he can get the Issur from a non-Jew, but if the only other option to buy it is from another Jew it reverts back to Lifnei Iver D'Oraysa (based on Mishneh LaMelech Malveh V'loveh 4:2 and R' Aharon Kotler, your Posek may differ, seems Ritva in Bava Metzia disagrees).</div>
<div> </div>
<div>All of the above is talking about a direct seller-buyer transaction, maybe someone can think of why a cashier is different - seems like it is still some sort of Siyu'a, but I don't know.</div>
<div> </div>
<div>I would think if there is a supermarket situation there are non-Jewish cashiers, and if it is a Mom and Pop kind of grocery there are probably others around, if it's the only one in Yehupitz and it will cost the guy more time and/or money to get it elsewhere, it seems like a serious Shaalah. </div>
