@sphennings That makes sense, and if I'm honest should be more a part of the answer (but I'm sure as hell not posting on this storm of a question!). So if I take this correctly (unlikely knowing me), then it's the time period that the clerk is known that is the real issue correct? For instance, if everyday I came to the shop, shared a couple words of hello and how are you, and left, at what point can I pose such a question. I'm just curious and can't be the only one who thought of it.
@rainbacon I work in a professional office for accounting in a medium sized construction company and frequently have to deal with consultants, vendors/suppliers, and clients. As a result, my interactions (and I'd suggest many others) are not solely confined to a single office.
