do you have something to gain weight.

Went there to git something quick and healthy to eat so i grab some pita bread and some hummus which came to about $4 or so. got to the register (didn't have any cash) and was told that I could only use the credit card for purchases of $5 or more!! What??!! Needless to say i walked out. Why is it that other places will accept credit card purchases for less than that? Whatever. Don't need my business.
