I`m sorry to say, but dealer fitted or not, these have to be way oversized. I`d say an inch maximum of space upfront after end of big toe. To go from 14 wide to 15B seems unusual. Did they have the full range of sizes, or they didn't have yours and had a 15B? You should try on a few pairs both up and down the size spectrum until you feel comfortable. Take them back and speak to a senior person at the store. Seems very unusual.
