how should a ‘christian’ business person act?

should this be a conundrum? i didn’t think so until the other day (2 days pre-christmas day) when my mom and i walked into a store sporting the ‘christian’ title 15 minutes before the listed closing time. of all the times i have slipped into a soon-to-close business, I have never received the greeting “we are closing in 5 minutes …blah, blah, blah” (basically please leave asap so i can ring out my till). we left the store in the allocated 5 minutes, then watched them turn away 3 shopping parties 2 minutes before the listed closing time. did i mention that this was happening 2 days before christmas?! strangely enough, my mom said it was about the third time she had received similar treatment from the employees of this particular store, and the reason wasn’t always the clock approaching closing time. for example, my parents had a major basement flood in the summer and she was shunned when asking for some help on book pricing in order to submit an insurance claim (which i really don’t think is too much to ask from someone who has not the know how or means to check pricing on the internet). my question is, what would a non-christian, or a person in desperate need think or feel if they received this treatment from someone who is assumed a christian based on the affiliation with their employment. actually, isn’t this just stupid business practice regardless your religious conviction? i guess lack of perceived competition with no other christian bookstores within a 50 km radius may contribute to lack of customer service, although i believe chapters and online christian bookstores may hold a slight price advantage … plus you wouldn’t have to deal with lovely ‘christian’ business people.
