add_filter( 'woofood_adjust_pickup_time_thankyou', 'wpslash_custom_hook_dynamically_change_pickup_time', 10, 2 );
function wpslash_custom_hook_dynamically_change_pickup_time( $time, $order_id ) {
	$store_id = intval(get_post_meta($order_id, 'extra_store_name', true));

	if($store_id == 1698)
	{

add_filter( 'woofood_adjust_delivery_time_multistore_checkout', 'wpslash_custom_hook_dynamically_change_pickup_time_checkout', 10, 2 );
function wpslash_custom_hook_dynamically_change_pickup_time_checkout( $time, $store_id ) {

	if($store_id == 1698)
	{
		 return "45";
	}
	if($store_id == 2688)
	{
		 return "30";
	}
	if($store_id == 2689)
