      *"Ich fahr dort hin gefreut das ich endlich mal bei diesem Bäcker was bestellen konnte. Wie gesagt ich war schon an der Tür **dann kam die Email ihre Tüten sind storniert**. Es waren noch drei andere da.  Die waren auch enttäuscht. Warum muss ich zwei Stunden vorher stornieren und die eine Minute".
      *"Toll sind auch Abholfenster von 5 Minuten".
      *"Aber: beim Kunden gibt es eine Stornierungsfrist von 2h damit die reale Chance besteht, dass jemand anderes die Tüte(n) dann noch 'übernimmt. Umgekehrt sollen ja in die Tüten Lebensmittel kommen die übrig sind und sonst vernichtet würden. Wenn dann eben kurzfristig doch alles verkauft wurde ist das für uns enttäuschend, aber ein bekanntes Risiko".
      *"Wir,Anbieter bei too good to go u auch Bäcker,mussten gestern auch 30min vor ABHOLUNG stornieren. a) ist dann erst absehbar das es nicht mehr reichen wird und b) hatte man bis dahin aufgrund dessen so einen Kundenandrang,das man keine Zeit hat an s Handy zu gehen.Aber wie gesagt,viel eher ist es bei uns auch nicht absehbar,das wir gleich ausverkauft sein werden zum Feierabend !!!".

      *"Du kannst sie bezahlen und dann nochmal über die kaufen. Also erst eine Tüte danach noch eine Tüte so haben wir das mal gemacht weil es bei uns auch nicht wollte das man gleich 2 bestellt".
      *"Das macht ein Bäcker hier in der Nähe auch. Du kannst pro Filiale immer nur eine Tüte kaufen. Da die aber in der Stadt mindestens 5 Filialen haben, mache ich immer eine Rundfahrt und nehme 2-3 Filialen mit".
