I mostly agree with what Mourning and Kurst have said on this thread; but for the most part "Gurella Fursuiting" in a private business puts me on edge in general. I'd just like to add a few specifics to the thread of what I've observed.

IMHO Places that should NEVER be considered to "public fursuit" at without WRITTEN CONSENT are:

-Malls (Most of these have VERY STRICT laws and ordinances about costuming)

-Zoos and Museums (As fun as it sounds, Most Zoos and Museums would view this as a distraction, and a pull away from their business.  We've ran into this issue in the past)

-Banks (Should be obvious here, There have been many robberies dealing with costumed characters)

-Jewelry, glassware, antique or other delicate stores (Tails plus China DO NOT mix…)

-Business Conventions (Unless they share a space with a Fandom con, which does happen XD)

-Professional Sports Games (Competing with the costumed mascot is not a wise idea.  Plus like malls most Stadiums have the "no mask" rule)

-Amusement Parks (Valley Fair, etc) (Its a controlled entry situation, and again you could be viewed as taking away business from the park, as with a Zoo, Museum, or Sports Event)

Places to Advise CAUTION, where I would still be uncomfortable with but you may or may not get escorted out of:

-Grocery and Department Stores (ones NOT part of a Mall)

-"Public" skyways, business Atriums

-Restaurants

-Minnesota State Fair (Unlike Renfest, the Fair has a lot of areas where a suit could impeed things)

-Bowling Alleys (While there are many fursuit bowling events, it is wise to call the bowling alley first)

-Municipal Sports Complexes with controlled entry (Ice Arenas, Golf courses, etc) (Like a bowling alley, with advanced notice these places could be acceptable to costumers.)

In general, use your head when suiting at a private business. This goes for any business I have not listed as well. Remember businesses are PRIVATE entities with their own set of regulations. The owner of the business has the right to kick out anyone at any time for any reason.

Most large businesses have security to prevent theft, property destruction and disserdants (IE a Drunk man wandering into Walmart harassing people)  In many of these situations, Costumers can be saw as the third type and be flagged for being escorted off the property.  I'm not here to say whether it's "right" of them to do so or not.  Just stating it as it is. 

I know many of those who view "calling up first" "ruins the magic of suprise".  Look at it this way.  If one manager knows you are coming and a few employees you are STILL going to be a surprise to the customers and your likelyhood of being accepted there and not being asked to leave goes up ten fold.

This all being said: In my mind, these places I have NO issues if I saw someone randomly show up in fursuit. 

-Public Parks

-Fandom Conventions where Costuming is acceptable (this includes Sci-Fi, Anime, Steampunk etc cons)

-Someone's House (if they were invited)

-A private party (again, invited)

-Outdoor events (Picnics, ETC)

-Events where Costuming is encouraged (Renfest, ETC)

-Nature preserves, Campsites.

-PUBLIC snow sledding/tubing hills (NOT ones with a controlled entry.  Places like the hill at Trapp Farm)

-Businesses during Halloween who have stated they accept costumers during this time.

-Costume balls/parties/contests/etc

Again, the real key is public vs private.  That line is sometimes not very clear, as the case with Como Park and Zoo.  The park is PUBLIC, but the zoo itself is a private entity with controlled access.  If your not sure if a place is a PUBLIC place or a PRIVATE entity ASK FIRST.
